Audi 80 B4 convertible from America for 8500 €

Hello everybody, short introduction: I am actually looking for an Audi A4 B6 convertible. Besides that, I always look for a B4 convertible, I drove a B4 limosine myself years ago, also a very nice car. In my search I found the following cars:http://bit.ly/1RC2DVu In short form: 74000 km, from America, 175 hp, automatic, repainted, various new parts. Now to my questions: Has anyone here experience with cars from America? What about the replacement In case of a defect of e.g. crossbars, exhaust, illuminant etc., can simply German spare parts be installed? What does it look like with underbody protection? What is there generally to consider with American cars? What is the general opinion, could the car be worth 8500 € in the described condition or is it clearly too expensive? I know we all don’t have a glass ball, I’m more concerned with subjective opinions. German cabrios in decent or good condition. The car is close to me, I would probably look at it once next week. Maybe you still have tips for the visit especially for this imported car. Thank you and greetings.
