Looking for a luxury car that won’t leave you stranded (or broke) after a few years? Mercedes-Benz has long been a symbol of prestige, but not all models age gracefully. If you’re shopping the used market, knowing which Mercedes models go the distance can save you thousands in repairs and headaches. As a mechanic who previously did hundreds of pre-purchase inspections on Mercedes, there are some models that stand out as the most reliable. Here are the top seven.
1. W124 E-Class (1984–1995)
The W124 E-Class is legendary for its over-engineered build and bulletproof reliability. Known as the “million-mile Mercedes,” this model has proven itself in harsh conditions worldwide. It features simple mechanical systems, durable engines, and timeless styling that still turns heads.
Maintenance is straightforward, and parts are widely available, making it a favorite among DIYers and collectors. If you want a classic Mercedes that truly goes the distance, the W124 is hard to beat.
2. W211 E-Class (2002–2009)
Next on the list is the W211 E-Class. This Mercedes blends modern luxury with dependable engineering. It offers advanced safety features, a refined interior, and a smooth ride that rivals newer models. Diesel variants like the E320 CDI are especially known for their longevity and fuel efficiency.
With proper maintenance, these cars routinely surpass 200,000 miles without major issues. It’s a smart pick for buyers who want a balance of tech and toughness.
3. W204 C-Class (2007–2014)
The W204 C-Class is a compact sedan that punches above its weight in reliability. It’s well-built, stylish, and offers a comfortable driving experience with solid fuel economy. The C300 and C350 models are particularly robust, with fewer electronic gremlins than earlier generations.
Owners praise its low maintenance costs and consistent performance over time. If you’re looking for a smaller Mercedes that won’t let you down, the W204 is a top contender.
4. W222 S-Class (2014–2020)
The W222 S-Class redefines what a luxury car can be, and surprisingly, it holds up well in the used market. Despite its tech-heavy design, this generation has proven more reliable than its predecessors. The S550, in particular, offers a powerful V8, plush interior, and advanced driver aids that still feel cutting-edge.
Regular servicing is key, but when maintained, this model delivers a first-class experience for years. It’s ideal for buyers who want the best Mercedes has to offer, without the new-car price tag.
5. W166 GLE (2012–2019)
For those in the market for a used SUV, you can’t go wrong with the W166 GLE. It is a midsize SUV that combines rugged capability with luxury appeal. It’s built on a solid platform and offers strong engine options, including the reliable V6 and diesel variants. Interior quality is excellent, and the ride is smooth even on rough terrain.
Many owners report high mileage with minimal issues, especially when routine maintenance is followed. If you need space, comfort, and durability, the GLE is a smart used buy.
6. X156 GLA (2014–2020)
Although I haven’t worked on any of these, the X156 GLA has had some praise from owners. It is Mercedes’ compact crossover that’s surprisingly tough for its size. It shares components with other proven models and benefits from a simpler drivetrain setup. The GLA250 is especially popular for its balance of performance and fuel economy.
It’s easy to park, fun to drive, and holds up well over time with proper care. For urban dwellers or first-time Mercedes buyers, the GLA offers a dependable entry point.
7. W123 300D (1976–1985)
You couldn’t kill the W123 300D with a gun. It is a diesel-powered legend that’s still running strong in many parts of the world. Known for its indestructible engine and simple mechanics, it’s a favorite among long-distance drivers and vintage enthusiasts.
These cars were built to last, often racking up hundreds of thousands of miles with minimal fuss. While not the fastest, they’re incredibly reliable and easy to maintain. If you appreciate old-school engineering, the W123 is a timeless choice.
Built to Last: Why These Models Stand Out
What sets these Mercedes models apart is their combination of engineering excellence and real-world durability. They’ve earned reputations not just from lab tests, but from owners who’ve driven them for decades. Whether it’s the tank-like W124 or the tech-savvy W222, each model offers a unique blend of reliability and luxury. Choosing one of these vehicles means fewer surprises and more miles of enjoyment. When buying used, it pays to pick a Mercedes that’s proven to go the distance.
