My car won't accelerate past 60 mph and slows down by itself. What could it be?

Hello! Did you ever get this resolved? I'm so sorry but somehow we missed this inquiry on this web site -- we typically get alerts for all European Motor Cars. We are just down the road from Jackson -- exit GA-20 toward lawrenceville -- we'll be happy to take a look. It sounds like it could possibly be transmission problem -- is it not getting into the high gear? Can you check the tachometer to see if it starts to hesitate in the "other gears" when say, it hits a high RPM (such as 4000 - 5000 RPM). There are many settings / adjustments in the computers of these cars that adjust the running of the car at different RPM levels. Could be a lot of things but let's get it in here and we can take a look (no charge inspection -- come and see us -- visit web site or call us for appt)
