I've always thought that selling a car is sort of like a test of character. Without getting too philosophical you can fix up something you're going to sell, tell the buyer about the potential problems you really know about or just say it's up to them to figure it out. I've always sold cars that I would drive anywhere. I've put money into cars that I won't get back just to know that I'm not trying to fool anyone. Maybe this is because I've been taken, so to speak, a few times. I personally think you'll think better of yourself and sleep better either fixing the known potential problems or letting the buyer know about them. Your call ???
