The Right Car

I am only 17 and dont have my own car yet. At first i had my mind set on a 3rd gen RX-7 but after reading about them and the rotary engine it has in it i figured maybe it wasnt a great idea to get for my first car ( not like i had to money for one anyway). Ive been looking at Celicas for a while now and decided that it seems like thats what im gonna go with. I like with 00 gt-s alot and i think its within my price range from what i have seen. I am very big into racing and will be attempting to tune up my car alot as the money comes along. I was wondering if anyone had any advice for me and if this is the right choice. How hard is it to tune these cars up and how expensive is it? Thanks

skip the celicas altogether. While they are quick, they arent fast.
