Being able to drive on the track, and being responsible enough not to use that speed on the street are two different things. The temptation to race is just too high.
If dad really has a F430 that you've been driving, I'm sure he won't head this advice and let you have whatever you want. At that point, I'd say go at least for the new E92 M3. Its faster than than the E46 M3 or 135i.
