You wouldn't have to part out the altered car if it's done right. People pay big money for them all together. And I like to think about it like this; Say you've been fed spaghetti for a good portion of your life.(spaghetti=altered cars). Then you get a taste and ability to afford steak.(steak=numbers correct/unaltered cars). You eat just steak for years.... You will eventually want some spaghetti again. And if the spaghetti is good enough, you may want it a lot. But the big question is: What is chicken?
