I will keep my ZL1, at some point if I want to go all in on tracking my car I could get the Z/28 tire, wheel and brake combo and some HP and some suspension work and I think you would have a car that would be very comparable to the stock Z/28 and still be able to reconfigure for the 1/4 mile and lose none of your DD comforts. So, from an economic standpoint I think I would stay with the ZL1. But from a desire standpoint yes I would love to have both. I think that is another of the ZL1's better points, it is so much easier to refit the ZL1 for your specific desires.
