The Mercedes-Benz GLE carries one of the longest continuous lineages in the luxury midsize SUV class, stretching back to 1997 when the original W163 M-Class (ML) rolled off the line in Vance, Alabama. That first model essentially invented the modern luxury crossover before the term existed, blending a body-on-frame-adjacent unibody with genuine off-road hardware.
In 2015, Mercedes renamed the W166 M-Class to GLE as part of a sweeping naming overhaul that tied every SUV to a passenger-car parent. The badge changed, but the bloodline did not.
Across four core generations — W163, W164, W166, and W167 — plus a deep bench of AMG and diesel variants, the GLE has swung from rugged trail-ready hauler to plush, screen-laden tech flagship. Buying one used in 2026 means navigating decades of engineering, some of it brilliant and some of it genuinely fragile.
Air suspension, balance-shaft wear, rust, and electronics gremlins separate the bargains from the money pits.
This ranking weighs reliability, performance, real-world running costs, and how well each generation holds up on the 2026 used market. The picks below cover the full sweep, from the cheap-and-cheerful early ML to the twin-turbo V8 AMG monsters and the modern 48-volt straight-six cars that define the current lineup.
Direct Answer
The best Mercedes-Benz GLE overall is the W166 GLE (2015-2019) — it took the proven W166 M-Class platform, added the GLE-era refinements, and arrived just as Mercedes had ironed out the early bugs, all while predating the most complex and expensive-to-fix electronics of the W167.
For the best value, the W164 ML350 (2005-2011) is the standout: a properly engineered, comfortable, and now genuinely cheap luxury SUV whose 3.5-liter V6 and conventional steel suspension keep maintenance sane. Below, all ten generations and variants are ranked with real specs and 2026 used pricing.
1. W166 GLE (2015-2019) 🏆 BEST OVERALL
The W166 GLE is the sweet spot of the entire lineage. Launched as a mid-cycle rename of the W166 M-Class, it kept the well-sorted platform that debuted in 2011 while gaining the 9G-TRONIC nine-speed automatic, updated styling, and the refined COMAND infotainment.
The volume GLE 350 ran a 3.5-liter naturally aspirated V6 making 302 horsepower, while the GLE 400 used a 3.0-liter biturbo V6 good for 329 horsepower. A diesel GLE 350d with the OM642 3.0-liter V6 delivered strong torque and 30-plus mpg highway.
By this generation, the early W166 teething issues were largely resolved, and the steel-spring suspension on base cars avoids costly AIRMATIC repairs. Reliability is the best of any GLE, and parts are plentiful. Expect to pay $18,000 to $30,000 for clean examples in 2026, making it the strongest all-around buy.
2. W167 GLE (2019-present)
The current W167 GLE is the most advanced and most luxurious the line has ever been. It introduced the MHEV 48-volt mild-hybrid system on its inline-six engines, a genuine leap in smoothness. The GLE 450 pairs a 3.0-liter turbocharged inline-six (M256) with EQ Boost for 362 horsepower and a brief electric torque fill that erases turbo lag.
The optional E-ACTIVE BODY CONTROL air suspension is the best-riding setup Mercedes builds. Interior quality, dual 12.3-inch MBUX screens, and rear-seat space all set class benchmarks. The catch is complexity: the 48-volt electronics, air suspension, and dense sensor suite make out-of-warranty repairs steep.
It ranks just behind the W166 purely on long-term ownership cost. 2026 used prices run $38,000 to $65,000 depending on year and trim, with low-mileage GLE 450 examples the smart pick.
3. Mercedes-AMG GLE 63 S (M177 V8)
The AMG GLE 63 S is the most ferocious GLE ever sold. Built on both the W166 and W167, the modern car uses the hand-built M177 4.0-liter twin-turbo V8 producing 577 horsepower and a colossal 561 lb-ft of torque in S trim, with the W167 version adding EQ Boost for short bursts.
Zero to sixty arrives in roughly 3.7 seconds, absurd for a two-and-a-half-ton SUV. The earlier W166 GLE 63 S used the M157 5.5-liter biturbo V8 at 577 horsepower as well. Both deliver thunderous exhaust, AMG SPEEDSHIFT transmissions, and serious chassis hardware.
Running costs are brutal — fuel, tires, brakes, and any V8 repair are expensive — which keeps it from ranking higher. On the 2026 used market, W166 cars start near $45,000 while W167 GLE 63 S models command $80,000 to $115,000.
4. W164 ML350 (2005-2011) 💎 BEST VALUE
The W164 ML350 is the smartest budget buy in the entire lineage. The second-generation M-Class moved to a fully independent unibody and dropped the troublesome early electronics for a far more polished package. Its 3.5-liter V6 (M272) makes 268 horsepower, paired with a smooth 7G-TRONIC seven-speed automatic.
Crucially, most ML350s ride on conventional steel springs, sidestepping the AIRMATIC air-suspension repair bills that plague higher trims. The cabin is comfortable, the 4MATIC all-wheel-drive system is genuinely capable, and parts are cheap and abundant after two decades of production.
Watch for the M272 balance-shaft issue on very early build dates and routine rust in salt-belt cars. With 2026 used prices sitting at just $5,000 to $10,000, no other generation delivers this much luxury SUV per dollar. It is the value champion.
5. W166 GLE 350d / ML Diesel (OM642)
The diesel GLE 350d and its ML250/ML350 BlueTEC predecessors are the long-haul value play. The OM642 3.0-liter turbo-diesel V6 produces around 255 horsepower but a stout 457 lb-ft of torque, hauling the GLE effortlessly while returning 28 to 32 mpg on the highway — figures no gasoline GLE approaches.
For towing and big-mileage driving, nothing in the range is cheaper to feed. The trade-offs are real: AdBlue systems, DPF regeneration cycles, and injector and turbo repairs can be costly if neglected, and emissions-era diesels carry resale stigma in some markets. Well-maintained examples with full service history are durable enough to clear 200,000 miles.
On the 2026 used market, expect $14,000 to $24,000, with documented service history the single most important factor in any purchase decision.
6. Mercedes-AMG GLE 53 (M256)
The AMG GLE 53 splits the difference between the comfort-focused GLE 450 and the brutal GLE 63. It uses the same 3.0-liter turbocharged inline-six (M256) but tuned to 429 horsepower with 48-volt EQ Boost adding a momentary 21 horsepower and filling low-end torque.
An electric auxiliary compressor and the mild-hybrid system make throttle response immediate, and zero to sixty takes about 5.2 seconds. Compared with the V8 cars, the GLE 53 is far cheaper to run, returns better fuel economy, and still wears genuine AMG suspension, brakes, and styling.
It rides on standard air suspension and gets sharper steering and a sportier exhaust note than the 450. The main downside is the cost of the 48-volt and turbo hardware out of warranty. 2026 used prices land between $48,000 and $70,000.
7. W166 GLE Coupe (C292)
The GLE Coupe (C292) brought a fastback roofline to the W166 platform, chasing the BMW X6 for buyers who prioritize style over outright practicality. Engine choices mirrored the regular GLE, from the GLE 350d diesel to the GLE 400 with its 3.0-liter biturbo V6 at 329 horsepower, up to the searing GLE 63 S Coupe with the M157 5.5-liter biturbo V8 at 577 horsepower.
The sloping roof costs rear headroom and cargo volume, and the standard AIRMATIC air suspension on many trims adds a repair risk. Styling is polarizing and resale softer than the standard body, which actually helps used buyers. It ranks mid-pack because the compromises are real, but a clean GLE 43 Coupe or GLE 400 Coupe offers strong looks and pace for the money.
2026 used prices run $28,000 to $50,000.
8. W166 M-Class (2011-2015)
Before the GLE rename, the W166 M-Class laid the groundwork that makes the later GLE so strong. The third-generation ML introduced a stiffer body, improved efficiency, and the move toward turbocharged engines. The ML350 ran a 3.5-liter V6 at 302 horsepower, while the ML550 packed a 4.6-liter biturbo V8 (M278) making 402 horsepower.
Diesel ML250/ML350 BlueTEC variants used the OM642 for excellent economy. Mechanically it is nearly identical to the early GLE, so reliability is good and parts overlap completely. The older infotainment and pre-facelift styling are the only real penalties versus the renamed car.
For buyers who want GLE substance at a discount, the W166 ML is a savvy choice. 2026 used prices sit at $10,000 to $18,000, undercutting the badge-equivalent GLE by a meaningful margin.
9. ML 55 AMG (W163, 2000-2003)
The original ML 55 AMG is the cult classic of the family and the first AMG-fettled M-Class. It crammed a hand-assembled 5.4-liter naturally aspirated V8 (M113) making 342 horsepower and 376 lb-ft of torque into the rugged W163 body, paired with a five-speed automatic and full-time 4MATIC.
At launch it was among the quickest SUVs on Earth, hitting sixty in around 6.5 seconds. The naturally aspirated M113 is one of Mercedes' most durable engines, and the analog driving character has aged into genuine charm. The downsides are W163-era build quality, dated electronics, rust, and thirsty fuel consumption.
It ranks here on collectibility and engine durability rather than everyday usability. Clean, low-mileage ML 55 AMG examples are appreciating, with 2026 used prices spanning $12,000 to $25,000 for the best cars.
10. W163 M-Class (1997-2005)
The W163 M-Class is where it all began, and it earns its spot on historical significance and dirt-cheap entry pricing. As the first Mercedes SUV, it offered genuine off-road ability with a two-speed transfer case and locking differentials, wrapped in a then-novel luxury package.
Engines ranged from the ML320 with a 3.2-liter V6 at 215 horsepower to the ML430 and later ML500 with a 5.0-liter V8 near 288 horsepower. The hardware is rugged, but W163 build quality and early-Alabama-plant assembly were the weakest of any generation, with electrical faults, rust, and interior wear common.
It is strictly a project or beater buy now, best for someone who wants cheap off-road capability and does the wrenching themselves. 2026 used prices are rock-bottom at $2,000 to $6,000, reflecting both age and risk.
What Separates a Great GLE From a Good One
The single biggest divider across every GLE generation is suspension type. Cars on conventional steel springs are dramatically cheaper to own than those on AIRMATIC or E-ACTIVE BODY CONTROL air suspension. Air struts fail with age, and a single corner replacement can run $1,500 or more in parts and labor; a full set on an older car can exceed the value of the vehicle itself.
A great used GLE buy almost always has either steel springs or fresh, recently replaced air components with documentation. Service history is the second great divider — a fully documented car with consistent oil changes, transmission services, and timely repairs is worth a substantial premium over an identical-looking neglected example, because German luxury SUVs punish deferred maintenance severely.
Engine choice and condition finish the picture. The naturally aspirated V6 and V8 engines like the M272, M113, and M278 are generally more durable than the most complex turbocharged and 48-volt units, though they trade away efficiency and outright power. On diesels, the health of the DPF, AdBlue system, and injectors makes or breaks the ownership experience.
A great GLE has had its known weak points addressed — balance shafts on early M272 cars, air struts, and electronics — while a merely good one is one failure away from a painful bill. Rust inspection matters enormously on W163 and W164 cars from salt regions, where corrosion can quietly total an otherwise running vehicle.
Buy the best-documented, best-maintained example you can afford rather than the cheapest one with the longest features list.
How to Choose
Start with your budget and tolerance for repair risk. If you want the safest all-around buy, the W166 GLE 350 on steel springs delivers modern comfort with proven reliability for $18,000 to $30,000. Shoppers on a tight budget should target a documented W164 ML350 at $5,000 to $10,000 and accept its age.
Big-mileage drivers and towers should seek a service-rich GLE 350d diesel, while performance buyers can stretch to an AMG GLE 53 for sane running costs or a GLE 63 S for maximum thunder. Whatever the generation, prioritize a pre-purchase inspection focused on air suspension, transmission behavior, electronics, and rust.
The right specific car always beats the right model on paper.
FAQ
Which Mercedes GLE generation is the most reliable?
The W166 GLE (2015-2019), especially the steel-spring GLE 350, is the most reliable of the lineage. Mercedes had resolved the early platform bugs by then, parts are plentiful, and it predates the most complex W167 electronics. A documented service history and steel suspension make it the lowest-risk used buy.
Is the GLE the same as the M-Class?
Yes. Mercedes renamed the M-Class (ML) to GLE in 2015 as part of a company-wide naming overhaul, with no change to the underlying W166 platform at the time of the rename. The badge changed but the bloodline is continuous, so a W166 ML and an early W166 GLE are mechanically near-identical.
Should I worry about air suspension on a used GLE?
Yes, it is the biggest cost risk. AIRMATIC and E-ACTIVE BODY CONTROL struts fail with age and cost $1,500 or more per corner to replace. Whenever possible, choose a steel-spring car or verify that any air components were recently replaced with documentation before buying.
Is the AMG GLE 63 worth the running costs?
Only if you genuinely value the performance. The M177 or M157 twin-turbo V8 delivers 577 horsepower and supercar acceleration, but fuel, tires, brakes, and any major repair are expensive. For most buyers the GLE 53 offers most of the thrill at far lower long-term cost.
Bottom Line
The Mercedes-Benz GLE rewards careful shopping more than almost any luxury SUV, because its long history spans both bulletproof and fragile examples. The W166 GLE (2015-2019) is the best overall pick for blending modern refinement with proven reliability, while the W164 ML350 is the runaway value champion at $5,000 to $10,000.
Performance buyers should weigh the manageable GLE 53 against the ferocious but costly GLE 63 S, and high-mileage drivers should hunt a documented GLE 350d diesel. Across every generation, the lesson is identical: prioritize service history, inspect the suspension, and buy the best-maintained specific car rather than the flashiest specification.
Do that, and a used GLE delivers genuine luxury for the money.
