"This has been a great car. It is comfortable yet, sporty. It was originally sold in Germany so it has some unique characteristics that the US version doesn't have. Mainly, it doesn't have a performance stealing catalytic converter. It needs work on the brakes, exhaust and fuel systems as well as the drivers seat."
