There is a TT advertised near me which has done 120k miles with full Audi main dealer Service history from new. However at 96k miles the cam-belt snapped and as a result a new engine was fitted for free as the car was still 3-days within it's warranty period! Now I am considering purchasing this car (providing the price is right), however I would be really interested to here peoples opinions on a car which as done 120k? As the engine has been changed would it be fair to say I could have a few years trouble-free motoring - or is the rest of the car going to be worn out too? Also, anything in particular I should look for in a 2000 (X) 225 Quattro?
