Excluding monthly payments, insurance, and gas (petrol); what is the general cost of ownership of one of these badboys? (Thinking of finally taking the plunge and getting one) - Tune-up - Clutch - Service - Oil consumption (I hear Jettas are terrible) - ... etc I know parts/service in general will be more expensive when compared to something like a Honda. How about known/common problem? I hear the moonroof fails a lot. I know there are a lot of 3er owners out there.
