There's a reason why insurance is high on GT's for 16 year olds. I know you can get in trouble in any car coz the problem is the driver not the car. But that's intentional trouble. The unintentional ones that catches you unaware and most likely will hurt you, your car, and others that you want to avoid.
Unless you go to some serious defensive AND high performance driving school, if I'm your father, I would start you off with an old sporty 4 or 6 banger that you can get rid of easily then move on to bigger ones.
I didn't like that idea myself when I was young but not that I am over 35 years old, I'm glad I took that route. Very glad indeed!
Oh yeah, I had my own unwarranted spills with my stick shift V6 Firebird. If it were a 315 hp V8 Trans
Am, I probably would be collecting lifetime disability early in life.
Even after all the driving experience I have. at 500 hp, I still catch myself sometimes using too much power where more lateral control is required instead.
I highly suggest you get an old BMW 3 series. I'll guarantee that it will keep you entertained much longer than you expect. If you don't mind driving a Miata's, that's a good one also. I've driven my friend's, and it was really fun. It really feels like being in a gokart or a big motorcycle.
Same thing applies with motorcycles. Been there, done that! Too much too soon almost sent me under a semi on the interstate.
