ahh the dichotomy of car building; start with something nice and original and alter the crap out of it or start with something terrible and alter the crap out of it... You are doing the right thing and will be happy you went this route. If you are at all concerned about it, just be very smart on what changes you make and pick proven combinations that do not chop the car up. That said, anything can be brought back if someone has enough money, however when you are done (assuming it done well) you will be exceptionally happy with it and enjoy the crap out of it. I also believe it will be worth far more than it is now.
