i think a lot of people do put the car back to stock because it seems to give them a bigger market. they also can sell the mods and get a little back from them. with some mods, you never know who did the work and if you can trust it. that tends to scare off a few people. to me part of the fun of modding a car is the research and then going on the hunt for it. i also enjoy the before and after results. some people dont mind a car with mods others do. more often the stock appearing car will sell faster. it would be nice to know of past mods on a car though, because who knows if the stock parts were reinstalled properly and if the car had any damage from the previous mods. this is just a guess and my opinion though. no real reasearch has been done on this on my part.
