...TT/(or new A5), Porsche Cayman. would like some opinions on options reliability, performance, and overall quality in order to make my decision.Thanks!

Personally I like the Sunfire.lower it put some racing stripes on it and a huge muffler and you have one kicking car!!! For like 50000 less than what your looking at. Dont forget, it will just rust out anyway. Use the saved money to buy some "good" times.

BMW 645i is a very good car, but it is very expensive it has a cel phone and i-pod charger, sunroof, and cruise control, and the Porche Cayman is economically good 4 the enviroment. so i'll go w/ the BMW 645i

the new audi are really nice and reliable. bmw got too much eletrical/censor malfunctions...maybe im just bad luck. don't know much about Cayman but it sure look like a lot of fun.
