Although technically an SUV, the unibody construction of the R-Class and its body styling make it appear more like a minivan.

Some of the models offered in this line include the R 280, R 350, R 500, R 63 AMG, R 320 CDI, and Germen spec R 320 and R 420 CDI 4Matic.

These cars are all based on the W251 chassis platform, but the R63 AMG is a performance model that stands out from the rest. It features a V8 engine that makes 503 horsepower paired with a 7G-Tronic 7 speed automatic transmission. It comes straight from the factory with "dubz" or 20 inch rims. With a 0 to 60 time of 4.6 seconds, this vehicle will run down most sports cars.

These vehicles have all been 4 wheel drive until 2007, when rear wheel drive versions were introduced.

These cars can be found on the used car market, although in limited quantities so far. The easiest place to find them is among the listings on eBay.
