The 1998 Mercedes-Benz C230 Sedan requires high test fuel yet has no power to speak of. Its gas milage stinks for such a small car. It is not very comfortable or roomy on the inside. This car would have been an OK choice for a single person. Its resale and trade-in values are terrible. If I would have done appropriate research beforehand and known all of these things I would have NEVER of purchased this car. It is surprisingly bad for one of the alledged higher end vehicles.
The C230 has minimal body roll.
Revamp the entire engine and transmission to get both better power and gas milage. Revamp the interior to give the car more room. Tall people cannot fit in this car unless they are in the front seat.
