9. E-Class W124 (1985-1995) (Exterior)
The Mona Lisa of Mercedes reliability that experts universally recommend.
Mercedes-Benz built tanks back when “safety features” meant avoiding a head-on collision, not haptic feedback. The E-Class W124 is their Mona Lisa of reliability; experts almost universally recommend it. Finding one with high mileage? That’s less a red flag and more a testament to its robust design.

Mechanically simple, built like a brick shithouse, and with proper maintenance, can outlive your Spotify Wrapped playlists. Think of it as the automotive equivalent of a Nokia phone—indestructible and eternally cool. The W124 remains the go-to for anyone prioritizing dependability over whether their car can parallel park itself.
8. C-Class W204 (2008-2014) (Exterior)
Mercedes did penance for past sins, delivering a luxury sedan without constant fear of expensive breakdowns.
The previous C-Class model had reliability issues that could make even a saint swear. Thankfully, Mercedes heard the complaints. With the W204, there was a deliberate return to quality. Updated engines showed better reliability, according to Consumer Reports and forum chatter. Think of it as Mercedes doing penance for past sins.

Specialists recommend the W204 for long-term ownership, which is always reassuring. As other luxury sedans of the era start showing their age, the W204 has the potential to age gracefully, maybe even becoming a future classic that doesn’t require a mechanic on speed dial.
7. GLK-Class X204 (2009-2015) (Exterior)
The SUV that’s as reliable as your grandma’s stories, with rugged simplicity and 150k+ mile potential.
Wondering what happens when you cross a G-Wagen with a C-Class? The GLK-Class X204 boasts rugged simplicity and a durable chassis borrowed from the W204 C-Class—making it less likely to throw a tantrum than your average reality TV star.

With proper maintenance, you’re looking at solid 150k+ miles of dependable service. Just steer clear of the early M272 engines, unless you enjoy playing mechanic on weekends. Think of the GLK as the sensible shoes of the Mercedes lineup: not flashy, but they’ll get you where you need to go, drama-free.
6. E-Class W213 (2017-present) (Exterior)
Promising modular engines and lightweight construction, but modern complexity means it hasn’t fully proven itself yet.
“Modern cars are incredibly complex,” says every mechanic who’s ever cursed at a wiring harness. The E-Class W213 rides that line between innovation and “I’m gonna need a bigger toolbox.” Promising modular engines like the M256 and M264, plus lightweight construction, this model hints at long-term reliability.
E-Class W213 (Interior)
Early adopters are basically beta testers with leather seats. The W213 is less “old reliable” and more “cutting-edge… maybe?” Its modern complexity means it hasn’t fully proven itself like the 1985 W124. But if you’re down to potentially spend $60,000+ for a car that might just outlive your patience with tech, this could be your ride.
5. S-Class W221 (2007-2013) (Exterior)
The Oval Office on wheels that ditched dodgy electronics, though it still demands a high repair budget.
The S-Class doesn’t just ferry CEOs; it’s basically the automotive equivalent of the Oval Office on wheels. The W221 generation took the baton from the W220, ditching that predecessor’s dodgy electronics like a bad habit. Thanks to improved components, this model promised less time at the shop.
S-Class W221 (Interior)
Finding a V8 model without the ABC (Active Body Control) or Airmatic suspension is like finding a decent reality TV show: rare, but worth the hunt. While it’s durable if maintained like a Swiss watch, potential owners should remember: owning an S-Class is like dating a supermodel—high maintenance, but undeniably impressive.
4. GLC-Class X253 (2016-2022) (Exterior)
The sensible shoes of the SUV world—practical, dependable, and trusted by families and businesses alike.
When your family’s SUV search feels like another episode of “House Hunters,” the GLC-Class X253 steps in. It’s a reasonable choice with a reputation for drivetrain reliability—not exactly the sexy sports car you fantasize about, but it won’t leave you stranded.

Running a small business? The GLC-Class X253 is the company car you can trust to keep running without major issues. The later years of this model are a solid pick for families and businesses needing a reliable ride without constant repairs.
3. C-Class W205 (2015-2021) (Exterior)
This generation got better the longer it baked, with 2017+ models hitting the sweet spot for reliability.
This generation Mercedes got better the longer it baked, like sourdough. Experts point to the models from 2017 onward as the sweet spot. With software glitches ironed out and build quality bumped up, those models are less likely to leave you stranded, cursing Stuttgart.
C-Class W205 (Interior)
Forums echo the sentiment that choosing the right engine is key. Avoid the four-cylinder gas units that sound like a sewing machine. Instead, aim for a V6 or even one of the diesel options, which apparently run forever, or until the government bans them, whichever comes first.
2. M-Class W164 (Exterior)
Like a sturdy Nokia—later years improved with better materials and rust protection, especially with steel springs.
Some folks treat old SUVs like ticking time bombs, but the M-Class W164 is more like a sturdy Nokia. While early models had their quirks, the later years stepped up their game with better materials and rust protection. Anyone who’s seen a W163 predecessor dissolve into orange dust knows that’s a low bar, but still.

The OM642 diesel is a beast, though watch out for those pesky emissions systems—they’re about as fun as a root canal. Sticking with steel springs instead of air suspension? Smart move for long-term reliability.
1. SLK (Exterior)
Post-2008 engines deliver coastal road carving without the drama of constant repairs that plague era rivals.
Ever fantasize about carving up coastal roads, wind in your hair? Post-2008 SLK engines give you just that, without the drama of constant repairs. This ride skips the overly complex systems that plague its peers, meaning you’re more likely to be enjoying the scenery than stuck on the shoulder.
SLK (Interior)
Compared to era rivals drowning in failures, the SLK is refreshingly straightforward. Instead of wrestling with gremlins, you’re experiencing its unique charm—and probably saving enough on maintenance to splurge on that beachside lobster roll. Drop the top and embrace the simple pleasures this roadster offers.
