I agree that Allen really has the right idea (scary though that may be) in that each design has its ups and its downs and that maybe combining some of them could be the way to go. It may still happen. I'm sure that the outcome of this thread, while very influential, will not put a gun to Jeff's head when it comes to finalizing the car.
Jason, there are always going to be haters, especially on the internet. You have no need to defend your work and your client list and portfolio prove that, but I'm preaching to the choir on this one. Good job not letting negative comments get you down and good work on the design.
