Car has left me stranded and in need of towing 5 times now in 3 years. It has so many electrical problems that no one can figure out, the last time I took it to the dealer for the same thing and spent $3,000 with no real fix. Looks good, is very fast but too heavy to be a real sports car, it drinks gas, and is very unreliable and expensive to own. Another thumbs down for Mercedes' recent product offerings, do you research and you'll find many reports of their shoddy quality in their modern cars.

Nav system needs improvement, electrical and electronic systems are absolutely terrible and need to be redesigned from scratch. Hire Lexus to figure out your reliability problems Mercedes.
