The '99 C280 Sport is an excellent mix of luxury and sportiness. Recent reviews of MB's have opined poor quality. However, in '99 MB built the C280 like it built Mercedes of old: rock solid. This car is an absolute joy to drive. The suspension is like no other car I've owned. The Sport version has a firmer suspension than the standard model. However, it remains a very subtle ride and sticks in corners adding fun. The V-6 engine takes premium fuel and I'm getting between 22MPG to 26MPG in mixed driving. The quality of the car is excellent. It looks new even though it is six years old.
Engine, suspension, quality, Bose sound, leather sport seats, paint quality.
Only wish I had the option to open rear seating area to trunk.
