It may be worth more if you find just the right buyer. Otherwise, most people like to buy stockers so they can do the mods. I typically stay away from modded cars as I never know the quality of work that was done. I just bought a bone stock 09 GT from the original owner. Had 78k on it which was high, but it also had the original tires still on it. Just that alone was a good indication of how it was driven. Now I can start my own mods..
