lol I sold an old Mustang convertible 15 years ago or so, and drove it 120 miles or whatever to where the old guy was going to look at it (had other business there). He's going over the car and I haven't done anything to it at all, from a cleaning perspective and he comes and says "that's the cleanest car I've ever seen. You're like me, everything has to be perfect. Even the wheel wells." He bought it on the spot. (Wish I had not sold that actually.) But I didn't clean those wheel wells (other than just hose them down).
