The third-generation wagon made its debut for 2004 and can be found in both E320 and E500 forms. Used Mercedes E-Class sedans and wagons can also be found with optional 4Matic all-wheel drive (it was standard on the E500 wagon until it was discontinued following the 2006 model). In 2005, the E55 AMG wagon was added, while in 2007, the AMG models got a larger V8 engine (507-horsepower, 0 - 60 mph in 4.3 seconds) minus the supercharger and were renamed the E63 AMG.
When Mercedes-Benz unveiled the CLS in 2003, the impact was significant. Not only was it singularly elegant, but it created a new category, that of the four-door coupe. Its success prompted many automakers, even those outside the luxury car category, to follow suit. If you want to put a figure on Mercedes-Benz's success, note that more than 170,000 units of the CLS have sold worldwide since its launch.
