HELP!!! Have asked a lot about the Audi TT!?!?!?

Hey people… I’m about to buy an Audi TT in winter! I’ve already been looking for everything to ask but I don’t really find anything because I just thought email and hope to answer! Yesterday I drove the 225hp test and I really liked it, would you recommend it to me or enough the 180s!? at what speed is it best to switch to burn the full power on the road!? where do I find good offers and how much would you now still have for e nn 225er spend!? how many kilometers should he have at most down!? would be happy if you could answer me quickly and answered my questions in detail! would really be happy… mfg marco
