Things that minor mean nothing to me, but to the general buyer this plays a big role. People are very picky, especially when purchasing something used-they feel they should be getting something "new"
Perfect example, I have a 95 M3 for sale, that makes roughly 600HP, it looks stock and is meant to be a sleeper. It has one purpose and that's going fast. A potential buyer said he probably wouldn't be interested in the car because it's in "rough shape" by rough he means a faded seat....... People are like this across the board when selling used cars, which is why if it's not a specialty vehicle I will just trade it in at a dealer and take a bath so I don't have to deal with people like that. I would walk to avoid headaches with re-sale, if you were keeping forever who cares, but that's not the case here.
