there's 2 trains of thought on buying a previously modified car

a) (rice aside) you get a modified car where the owner took the loss on the money spent on aftermarket parts...if you did it yourself (even all the labor) you'd spend alot more with the price of the car than what you got...my experience if you want to buy a race car (a real track only race car) i'd buy one that was already prepped as you'll spend a lot less money in the long run

b) where 4gh was saying is you learn lots yourself about doing your own modifications and get to pick and choose what you want done
