I appreciate my enthusiasm towards my 300ZX. There is a big difference. I'm not going to place my car on a pedestal. Yes, it is a beautiful car with beautiful design in both body and performance but in the end it is still just a car. It is the same as any other car. There are many cars out there that look better AND perform better but we just ignore them. Is it because we are ignorant? NO! It is because we have a love for the Z and that is where we focus our enthusiasm. I say if you want to modify your car then go ahead and modify it. If you want your enthusiasm to be geared different than some but the same as others, go for it. There is nothing holding you back. The Z will not be mad at you for changing it's appearance. It will still perform just how you want it to. The only thing that will perform different are the people flaming you for doing somethign outside their taste.
BTW, think about this. Why is it okay to change the performance of our car from stock but not the body? Is it okay to want to be a Ferrari in performance but rice to want to be a Ferrari in body? Where is the line drawn and who exactly is the one drawing it?
