I prefer to buy hail damaged vehicles. Something that's been hit while it's in the dealer lot is AWESOME. I'm married, not trying to impress anybody, no purpose for cosmetics at this point. And yeah, I don't spend a weekend waxing it.
Note, I'm not ripping on the people who do, different strokes for different folks. Sometimes it may be useful to ask yourself what's the real motivation behind some of the things we do though.
