The second-generation Mercedes-Benz M-Class, known as the W164, was sold from 2005 to 2011. It represented a huge step forward from the original W163, ditching the body-on-frame construction for a more refined unibody platform. This change vastly improved its on-road manners, ride comfort, and safety, making it a direct competitor to other premium SUVs of the era. Engine choices were plentiful, ranging from the popular ML350 with its 3.5L V6 to the torquey ML320 CDI diesel and the V8-powered ML550.
The W164's collectibility is almost entirely centered on the high-performance ML 63 AMG. Powered by the legendary 6.2L naturally aspirated M156 V8, it produced 503 horsepower and could accelerate from 0-60 mph in under 5 seconds. It combined the practicality of a 5-passenger SUV with the soul of a muscle car. As values for cars with the M156 engine rise, the ML 63 is gaining attention from enthusiasts looking for a unique and powerful family hauler.
Today's market for the W164 is sharply divided. The vast majority of transactions are for non-AMG models, which have depreciated significantly and trade for an average of just under $10,000. They are treated as used luxury vehicles rather than collectibles. The top of the market, reaching over $34,000, is exclusively for well-preserved, low-mileage ML 63 AMG examples. These are the cars that have the strongest potential to hold or increase their value.
Buying Tips
- Check the optional Airmatic suspension for sagging corners or a constantly running compressor, as leaks are common and costly to fix.
- For ML 63 AMG models, verify if the engine's head bolts have been replaced, as early M156 V8s are prone to failure.
- On pre-2007 ML350s, listen for engine noise that could indicate balance shaft gear wear, a significant and expensive repair.
- Test all electronic features thoroughly, including the COMAND system, power liftgate, and parking sensors, as failures are common.
- Inspect the 7G-Tronic transmission for smooth shifts and inquire about service history, as conductor plate issues can cause jerky operation.
Prices range from under $5,000 for high-mileage V6 models to over $34,000 for top-spec, low-mileage ML 63 AMG examples.
