2007 Mercedes-Benz CLS-Class CLS550 4dr Sedan (5.5L 8cyl 7A)
I've owned 10 vehicles over the last 25 years and the CLS550 is unquestionably the biggest disappointment. Bottom line - I've got an $80,000+ luxury vehicle with all the bells and whistles that drives like a 1972 Fiat. Despite being in the shop 3 times in the first 90 days, the vehicle continues to violently rattle and vibrate, the "premium sound system" sounds like a transistor radio, and the "climate controlled seats" are nothing more than a weak fan with an imperceptable effect. Two thumbs down!
Exterior design, profile.
Improve interior design. Reduce noise/rattling. Improve stereo system. Increase side mirror size. Drastically improve navigation system. Install true climate control system in seats
