Absolutely nothing, and this car is driven a lot!
I'm actually writing this review on my boyfriend's car. He used to have a 1995 Accord that got merged into by an 18-wheeler, and when he went looking for a replacement after the car was totaled, I begged him to at least look at the Stratus R/T.
I have personally put a lot of miles on the car while he's out at sea (submariner), and I absolutely love this car. It's quick, responsive, very comfortable (except for the cup holder right behind the shifter) and looks great too. All he's done to the car is tint the windows, but that's all it needed. I would definitely recommend the car to someone looking for a distinctive style that's fun to drive and easy to maintain.
The only complaint I have is the lack of after-market performance parts available for the car.
There are more after market for that car than you think go to dreamspeed2.com you will find things there I have a 2001 r/t and I put a cold air intake and under drive pulleys on it and a spoiler off a 98 eclipes and that looks sweet I also purchased a body kit for it and 18" wheels it's a one of a kind r/t.
