Unforutnately mods and add on's only add value to the "right" buyer. If you find yourself the perfect buyer then they'd be happy to give you extra. However the reality is... most of the time these things don't add to the vehicle. Think about someone looking for a reliable car, they may question why a motor blew. How long do you think they stick around after they hear the car was running fast times in the 1/4 mile? They will assume beat to a pulp everything instead of the upgraded items on the car.
