Hey guys, i'm drew. I'm about to get my permit (i just turned 15)

and will probably be getting a nissan for my first car. Dont worry i'm not here to join the "mad tyte" bandwagon, i'd more like to get into roadracing, autox, and time attack stuff.
i was thinking of getting a early 240sx or 80s 300zx, you guys think thats a good choice?
thanks,
Drew
