I am in the used market and I am deciding between a 9-3 and an Audi TT. Has anyone owned/driven both that can give me a honest comparison? Thanks.

 

I had a TT convertible for about 3 years. Fantastic car. Only 'deficit' is its small size and sorely limited storage space.
Compared it to my current 9-3, the TT is a true sports car that has brilliant handling and road feedback.
The 9-3 is a very nice car but it is a front wheel vehicle that has 'heavy' steering and anything but a sports car.
The TT and the 9-3 are two different birds of a feather. You must decide which is best for you.
