The Mercedes-Benz E55 AMG (W211) pairs a remarkably durable supercharged V8 and five-speed automatic with 469 hp and 516 lb-ft of torque. Its drivetrain remains one of AMG’s strongest, but that doesn’t make the entire car equally dependable. Two decades later, air suspension, electrohydraulic brakes and aging electronics can cost more to maintain than the … Read more
The C63’s reliability depends heavily on its generation. The W204’s 6.2-liter M156 naturally aspirated V8, W205’s 4.0-liter M177 twin-turbo V8, and W206’s four-cylinder plug-in hybrid have fundamentally different engineering and repair risks. For used buyers, I’d start with a well-maintained 2012–2014 W204 or 2019–2021 W205. Neither is cheap to maintain, but their known weaknesses are … Read more
The 2011 Mercedes-Benz C300 remains an appealing used luxury sedan, particularly for buyers who prefer a naturally aspirated V6 over modern turbocharged four-cylinders. Its 3.0-liter M272 engine delivers smooth performance, while the W204 chassis offers a solid balance of comfort and handling. But is the 2011 C300 reliable? Generally, its engine and transmission can deliver … Read more
The 2005 Mercedes-Benz C230 Kompressor remains an appealing inexpensive entry into older Mercedes ownership. Its 189-hp supercharged four-cylinder, rear-wheel-drive chassis and available six-speed manual give it more character than its current price suggests. But one mechanical weakness can change the ownership equation: the M271 engine’s timing chain and camshaft-adjuster sprockets can wear enough to cause … Read more
Here is our updated list of the most reliable AMG cars, revised to prioritize proven powertrains, mechanical simplicity, and long-term durability. If reliability comes first, the M113 V8 era remains an excellent place to start, combining a proven naturally aspirated engine with fewer layers of complexity than later turbocharged AMGs; several models also used Mercedes’ … Read more
The GL450 can be an appealing used three-row luxury SUV, but reliability depends heavily on the engine and model year. U.S. versions used three distinct powertrains: the M273 naturally aspirated V8, M278 twin-turbo V8, and later M276 twin-turbo V6. If I were buying one today, I’d start with a well-maintained 2015–2016 M276-powered GL450. A sorted … Read more
The 2020 Mercedes-Benz C300 remains an appealing used luxury sedan, combining strong turbocharged performance and a refined cabin with the mature W205 platform at a much lower price than a newer C-Class. Reliability is reasonable if the engine, transmission, and electronics check out, but this isn’t inexpensive transportation. Condition and maintenance history matter more than … Read more
The E350 BlueTEC’s 3.0-liter OM642 turbodiesel V6 can cover substantial mileage, but engine durability doesn’t make the entire car trouble-free. Oil cooler seals, intake swirl mechanisms, the DPF, and AdBlue/SCR hardware can generate expensive repairs even while the engine itself remains mechanically healthy. That’s the key distinction for used buyers: a durable diesel engine doesn’t … Read more
The Toyota Sequoia leads iSeeCars’ September 2026 longevity study with an estimated 42.3% chance of reaching 250,000 miles, followed by the Toyota 4Runner at 33.1% and Lexus RX Hybrid at 28.9%. The study analyzed more than 395 million vehicles, while the average SUV scored just 4.8%. But longevity alone doesn’t determine the smartest long-term purchase. … Read more
The Mercedes-Benz C-Class can be an excellent used luxury sedan, but powertrain choice matters as much as generation. The 2012 C250 and C350 share a chassis yet carry very different engine-related risks. For reliability, I’d favor the 2012–2014 C350 or 2013–2014 C300 4MATIC, both with naturally aspirated M276 V6 engines. The 2019–2021 C300 offers a … Read more
