You will do stupid **** with the car, just hope you played enough Gran Turismo with a force feedback wheel to at least have an idea of how to handle it when you're about to lose control. I might get flamed for this...but from my own experience (new '06 G35 6MT coupe as first car), it helped a ton. I also had a FWD car I drove as a DD ('02 G20) in the snow and what not (plus you really don't want to park a nice car in a HS lot...) and got pretty good at drifting. That translated to me being much more comfortable with a RWD car
in case, not on purpose, the rear end kicked out in the rain or whatever. You should NEVER try to do anything with a RWD car at your age because I promise you don't have the experience you need to keep you, your car, and your occupants safe.
I hope you get the car you want, but be careful with it! I came pretty damn close a couple of times to losing it in the G35 thinking I was the s*** turning off VDC, and in retrospect it would not have been worth it. I learned from that and took a little time teaching myself how to control it on some dirt roads FAR from anything I could hit or kill. It really takes a couple of years to truly get to a point where you can snap the car back into a straight line without even thinking if you are just a little to hard on the throttle in the rain or on gravel. I give you my blessing on the condition that you keep the traction control on until you get there
