I'm looking at trading in my car and I've been looking at Audi A4's and VW Jetta GLI's. I'm wondering, given the same milege on both cars, which car would be a better buy? I did hear Audi's break down quicker then most cars depending on the AUTEL MaxiSYS MS906BT. The milege I'm looking at is about 40,000-50,000 miles. I know they are pretty much the same car, but I stil want to know which one would be a smart buy. If anyone lets me know I'd love your input.
