Mercedes-Benz 400E Reviews
These cars are amazing and mine is in immaculant condition having 142k miles and its a 1992 400E. They run and drive excellent and have low maintenance even for its age! Definitely recommend this auto
I just bought it after hitting a deer and totaling my 300E. The A/C doesn't work. It's quite a car but climate control has not been their best effort. It has aftermarket shocks. I want my Bilsteins back.
