Top 10 Grand Tourers 1974 — Best Overall + Best Value

1. Mercedes-Benz 450SLC 5.0

The 450SLC 5.0 ranks first because it was the only 1974 grand tourer that combined rally-proven durability with genuine 200-plus km/h cruising. Its 5.0-litre V8 produced 240 hp, enough for 0-100 km/h in roughly 8 seconds, and it won the 1978 Vuelta a Espana outright. The C107 platform used a shortened S-Class floorpan with a fully independent suspension and four-wheel disc brakes.

This car is for the buyer who wants a homologation special that can cross a continent at speed yet still be serviced by any Mercedes specialist. It trades away rear-seat space and fuel economy for that capability. Compared to the Jaguar XJC below it, the Benz is heavier and less elegant, but far more robust mechanically and considerably rarer in 5.0 form.

2. Jaguar XJ-S

The Jaguar XJ-S takes second because it delivered V12 refinement at a price no rival could match in 1974. Its 5.3-litre V12 made 285 hp and pushed the 1,700 kg coupe past 240 km/h, making it one of the fastest production GTs of the year. It rode on a sophisticated independent rear suspension and used four-wheel ventilated discs. Fuel consumption was notoriously heavy, around 18 L/100 km.

This is for the enthusiast who values smoothness and presence over outright reliability and running costs. It gives up the Mercedes' durability and parts availability, and the V12 requires specialist maintenance. Against the BMW 3.0CSL below it, the Jaguar is faster and more luxurious but heavier and thirstier, with a less sporting chassis balance.

3. BMW 3.0CSL

The BMW 3.0CSL places third because it was the most driver-focused grand tourer of 1974, a homologation special that dominated European touring car racing. Its 3.0-litre straight-six produced 206 hp, and lightweight aluminium body panels cut roughly 200 kg versus the standard CS. It won the European Touring Car Championship six times between 1973 and 1979.

This car suits the purist who wants a manual gearbox, rear-wheel drive, and a race-bred chassis over luxury. It trades away the V12 smoothness and cabin opulence of the Jaguar above it, offering a harsher ride and less sound insulation. Against the Porsche 911 below, it is more practical and comfortable but slower and less precise in fast corners.

4. Porsche 911 Carrera 2.7

The Porsche 911 Carrera 2.7 ranks fourth because it blended grand touring usability with sports-car pace better than almost anything else in 1974. Its 2.7-litre flat-six produced 210 hp in European trim, giving 0-100 km/h in about 6.5 seconds and a top speed near 240 km/h. The ducktail spoiler and wider rear arches came from the Carrera RS programme.

This is for the driver who wants a usable classic that still feels alive on a mountain road. It trades away rear-seat comfort and luggage space compared to the BMW above it, and the rear-engine layout demands respect in the wet. Against the Citroen SM below, the Porsche is more reliable and faster but far less exotic in its engineering.

5. Citroen SM

The Citroen SM earns fifth because it was the most technically radical grand tourer of 1974, pairing a Maserati V6 with hydropneumatic suspension. Its 2.7-litre engine produced 180 hp, enough for 220 km/h, and the self-levelling suspension gave extraordinary ride quality. It also featured DIRAVI variable-ratio power steering and inboard front brakes.

This car is for the collector who prizes engineering novelty and comfort above all else. It trades away parts availability and simplicity, as the Maserati engine and hydropneumatic system demand specialist care. Compared to the Porsche above it, the SM is more comfortable and spacious but slower, thirstier, and considerably more expensive to maintain.

6. Aston Martin V8

The Aston Martin V8 ranks sixth because it offered muscular British grand touring with a 5.3-litre V8 producing around 280 hp. It could reach 240 km/h and hit 100 km/h in about 6.5 seconds, making it one of the fastest GTs of 1974. The engine used four Weber carburettors, and the car rode on a sturdy platform with a live rear axle.

This is for the buyer who wants presence, hand-built character, and a thunderous V8 soundtrack. It trades away handling finesse and fuel economy, and the live axle feels crude next to the Citroen's hydropneumatics. Against the Jensen Interceptor below, the Aston is more prestigious and better finished but slower, heavier, and far more expensive to restore.

7. Jensen Interceptor

The Jensen Interceptor takes seventh because it delivered American V8 muscle in an Italian-styled British fastback. Its 7.2-litre Chrysler V8 produced around 250 hp, and the car could exceed 220 km/h while seating four in genuine comfort. It used a three-speed TorqueFlite automatic and four-wheel disc brakes, with a distinctive curved rear glass hatch.

This car is for the buyer who wants effortless torque, low running costs, and a practical hatchback layout. It trades away the Aston's prestige and the Citroen's sophistication, offering vague steering and heavy fuel consumption. Compared to the Mercedes above it, the Jensen is cheaper and simpler but less durable and considerably less refined at speed.

8. Lamborghini Espada

The Lamborghini Espada ranks eighth because it was the fastest four-seat grand tourer of 1974, powered by a 3.9-litre V12 producing 350 hp. It could reach 250 km/h and accelerate to 100 km/h in around 7 seconds, remarkable for a car with genuine rear seats. The Espada used a tubular chassis and independent suspension, with disc brakes all round.

This is for the collector who needs four seats but refuses to sacrifice V12 drama. It trades away reliability and parts availability, as Lamborghini's V12 requires frequent specialist attention. Against the Jensen above it, the Espada is far faster and more exotic but thirstier, less practical, and much more expensive to keep on the road.

9. Ferrari 365 GT4 2+2

The Ferrari 365 GT4 2+2 places ninth because it brought Maranello's V12 into a practical four-seat grand tourer. Its 4.4-litre V12 produced 320 hp, giving a top speed near 250 km/h and 0-100 km/h in about 7 seconds. It used a five-speed manual or optional automatic, with independent suspension and four-wheel disc brakes.

This car is for the buyer who wants Ferrari heritage with room for two occasional rear passengers. It trades away the Espada's outright pace and dramatic styling for more discreet Pininfarina lines and better build quality. Compared to the Lamborghini above it, the Ferrari is more usable and better assembled but slightly slower and less flamboyant.

10. De Tomaso Deauville

The De Tomaso Deauville ranks tenth because it offered Italian styling with Ford V8 reliability in a four-door grand tourer. Its 5.8-litre Cleveland V8 produced around 300 hp, and the car could reach 230 km/h while carrying four adults in comfort. It used a ZF five-speed manual or Ford automatic, with independent suspension and disc brakes.

This is for the buyer who wants exotic looks and American mechanical simplicity at a fraction of Ferrari running costs. It trades away brand prestige and parts availability, as De Tomaso's dealer network was always thin. Against the Ferrari above it, the Deauville is cheaper and easier to maintain but slower, less refined, and far less desirable to collectors.

How we ranked these

We scored each 1974 grand tourer on a 100-point scale: 30 points for powertrain output and delivery, 25 for chassis balance and steering feel, 20 for real-world usability (seating, luggage, visibility, ride), 15 for braking and tire-era grip, and 10 for parts availability and club support. Data came from period road tests, factory specifications, and current owner reports.

We deliberately ignored auction hype, celebrity provenance, and color rarity, because those inflate asking prices without improving the car. We also excluded modified cars, trailer queens, and anything needing a specialist just to start. The goal was a usable GT you could actually drive weekly, not a garage ornament judged only by its hammer price.

What to look for

Prioritize rust inspection over paint, especially in the cowl, rockers, floor pans, and rear shock towers, since 1970s steel and drainage were poor. Then verify the cooling system, carburetor condition, and electrical grounds, because those three areas cause most breakdowns. A compression test and oil analysis tell you more about engine health than any service receipt.

The mistake most buyers make is paying for cosmetic restoration while ignoring deferred mechanical work. A shiny respray can hide filler over rot, and a rebuilt interior says nothing about synchros, bushings, or brake lines. Budget 25 to 40 percent of the purchase price for immediate sorting, and walk away from any car whose owner refuses a cold start or a lift inspection.

Related questions

What was the best overall grand tourer of 1974?

The Mercedes-Benz 450 SLC combined a fuel-injected V8, a rigid closed body, and genuine 130 mph cruising with room for luggage. It was heavy and thirsty, but it delivered the most complete GT package that year, blending comfort, safety, and durability better than lighter rivals that demanded more attention and maintenance.

Which 1974 grand tourer offered the best value?

The Datsun 260Z delivered six-cylinder performance, independent suspension, and respectable reliability for a fraction of European prices. Rust and carburetor tuning are its weak points, but parts remain cheap and widely available. For a buyer wanting usable GT character without exotic running costs, it was and still is the value benchmark.

Was the Porsche 911 a grand tourer in 1974?

The 911 was evolving toward GT duty, and the 1974 2.7 models added torque and comfort. It remained more sports car than tourer, with a cramped cabin and tricky rear-weight bias. Buyers wanting pure driving engagement ranked it high, while those prioritizing long-distance comfort placed it behind larger coupes.

How did the Jaguar XJ-S compare in 1974?

The XJ-S launched with a smooth V12, superb ride, and striking styling, but early cars suffered cooling, fuel, and electrical faults. It offered tremendous value per cylinder and effortless cruising. Buyers who sorted the cooling and ignition found a superb long-distance GT, though running costs and complexity kept it from the top spot.

What about the BMW 3.0 CS in 1974?

The BMW 3.0 CS paired an inline-six with elegant proportions and strong build quality. It was lighter and more agile than the Mercedes, with better steering feedback. Rust in the body shell is the primary concern, and good examples command strong money, but it remains one of the most balanced GTs of the era.

Did American cars qualify as grand tourers in 1974?

The Chevrolet Corvette and Pontiac Firebird offered V8 torque and low prices, but soft suspension, poor brakes, and thirsty engines limited their GT credentials. The Corvette's fiberglass body resisted rust and its parts were cheap, yet refinement and luggage space trailed European rivals. They scored well on value, less on touring polish.

Which 1974 GT is easiest to maintain today?

The Datsun 260Z and Chevrolet Corvette are easiest, thanks to simple mechanicals, huge parts networks, and active clubs. Mercedes and BMW parts are available but pricier. Jaguar V12 and Porsche flat-six work demands more specialized knowledge, so factor in labor costs and local specialist availability before choosing.

How much should I budget beyond the purchase price?

Plan on 25 to 40 percent of the purchase price for immediate sorting: cooling, brakes, tires, fluids, bushings, and electrical repairs. A cheap car with deferred maintenance usually costs more than a well-sorted example. Pre-purchase inspection by a marque specialist is the single best way to avoid a costly surprise.

FAQ

What defines a grand tourer versus a sports car?

A grand tourer prioritizes comfortable long-distance travel with luggage space, refined powertrain, and stable high-speed manners. A sports car prioritizes agility, light weight, and driver engagement, often sacrificing comfort and practicality. Many 1974 models sat between the two, so we weighted usability alongside performance when ranking them.

Was 1974 a bad year for performance cars?

Yes, in many ways. Emissions controls, lower compression, and safety bumpers sapped power from American and some European models. Fuel crises pushed buyers toward economy. Still, strong GTs survived, including the Mercedes 450 SLC, BMW 3.0 CS, Jaguar XJ-S, Porsche 911, and Datsun 260Z, all offering genuine character despite the climate.

Which 1974 GT has the best parts availability?

The Datsun 260Z and Chevrolet Corvette lead, with reproduction and NOS parts widely sold through major suppliers and clubs. Mercedes-Benz and BMW also support classics well through factory heritage programs. Jaguar and Porsche parts exist but cost more, and some V12-specific components require specialist sourcing or rebuilding.

Are 1974 grand tourers a good investment?

They can be, but only well-sorted, original examples with documentation. Rust-free Mercedes 450 SLC, BMW 3.0 CS, and early XJ-S cars have appreciated. Modified or rough cars rarely reward owners. Treat investment as secondary to enjoyment, and buy the best example you can afford rather than the cheapest project available.

What should a pre-purchase inspection cover?

Compression and leak-down tests, cooling system pressure check, brake and suspension inspection, rust assessment in structural areas, electrical function, and a cold start. For fuel-injected cars, verify injection operation and fuel pressure. For V12 Jaguars, check cooling and ignition thoroughly. A specialist inspection costs little compared with repairing hidden faults.

How do running costs compare across these cars?

Datsun and Corvette are cheapest, with simple parts and easy service. BMW and Mercedes cost moderate amounts, with quality parts but higher labor. Porsche requires specialist knowledge and pricier components. Jaguar V12 is thirstiest and most complex, often needing cooling, ignition, and fuel system attention. Budget accordingly before buying.

Can these cars handle modern traffic and fuel?

Most can, with caveats. They lack overdrive gears, so highway revs are high, and carbureted or early fuel-injected engines dislike ethanol blends. Cooling systems struggle in stop-and-go heat. Upgrading radiators, fans, ignition, and tires transforms usability. Lead-free fuel is generally fine on later 1974 engines with hardened valve seats.

Which 1974 GT is best for tall drivers?

The Mercedes 450 SLC and BMW 3.0 CS offer the most head and leg room, with adjustable seats and upright driving positions. The Jaguar XJ-S is tighter but workable. Porsche 911 and Datsun 260Z are cramped for taller drivers, especially with sunroofs. Sit in each model before buying, since seat rails and aftermarket seats vary widely.

How important is originality when buying?

Originality matters for value and for understanding how the car should drive. Correct engine, transmission, and interior trim support resale. However, safety upgrades like better tires, brakes, and cooling are sensible and rarely hurt enjoyment. Avoid cars with undocumented engine swaps or structural modifications unless the price reflects the compromise.

What is the biggest mistake first-time buyers make?

Falling for shiny paint and ignoring mechanical and structural condition. Rust, tired cooling systems, and neglected brakes cost far more than cosmetics. Another common error is buying the cheapest example rather than the best. Pay for a thorough inspection, drive several cars, and choose the one with the strongest maintenance history.
