I have been lurking on this forum for a while as I am planning on getting a boxster soon... so this is my first post
Try Autodynamica on 290... a friend of mine had his Audi A4 serviced there and said they were cheap and they had 2 996TT there, one for regular stuff and the other was a Evo GT800 they did...
Welcome to the board! We should get together some time soon. Have you gone to a dealership to drive one yet? I'd do that right away. If for no other reason, it will give you all the energy you need to save up for one.
I bought mine knowing I'd love it and never drove one before I had my keys in my hand.
