It has been my experience with past cars, and with friends with high dollar cars (Ferrari, Lambo, Porsche) that doing mods, from body work to high end engine work does not increase the market value of the car. You do the mods because it's what you want to do. You want the look or the power. But don't expect the cost to transfer over to the value of the car because it just doesn't happen. I think the guy that traded it in or sold it found out that harsh reality. It's being sold cheap because he got fair market value for his Viper at stock. The exception to this is finding that buyer that wants that car, with those mods, and can get it cheaper than what he was going to pay to have it done. That's a rare buyer. Trading a car in to a dealer will net you zero almost every time for every dime you spent on mods. Dealers want them stock all the way down to the wheels. There are always exceptions of course but that's what they are, exceptions. That car may sell at that 60k but to be honest, I'll be suprised if it does. Have to find that right buyer who is dying for a Viper and wants those mods and has the money. Once again, you do the mods because you want them. I will likely do some to my car. It's want I want looks and performance wise, but I also understand it won't increase the market value of my car.
