If your looking for something for just the track there are much less expensive cars that you don't have to worry about high repair/maintenance bills that will out perform/be very close to those you have listed such as a s2000, e30 anything, e36 m3, e46 m3. I'm sure you want a fly car too, but if its just dedicated track car why risk throwing your 430 into a tire wall and then having to pay thousands for repairs?
