Im not sure exactly how much a clone ZL1 would be worth, but… I would have to say that it would be worth getting a loan to do it right, just because the pay off will be so high. Thats if your looking to make money. If you are looking to keep the car, then I would wait, take the time and do it right, there is no reason to not do that car 100%. Its an investement… and im sure you know that. Its nice to see someone else younger interested in these rare camaros.
