Yes, the 996TT's are great cars, but repair costs are HUGE!!! My DD is a Porsche and I would never "go naked" without a factory warranty on one of these cars. Hell, my summer wheels cost $6,500 alone!!! A buddy just did a tranny in his '02 TT and it cost $10K...
I bought a 3 year, 36,000km warranty on the Z06 for about $1,800 bumper to bumper with $100 deductable. So, I think I have the repair cost angle covered
