I've never been careful with my guitars, or cared if they were pristine. I've always preferred the lived-in look. That's one of the reasons i bought my first Telecaster in 1991 instead of a paper-thin Ibanez shredder. It FELT more substantial.
I bought a '74 Tele specifically because the PO had played it for over 2 decades gigging regularly. it's got beautiful wear-spots, has turned orange from the nicotine in bars, and has a life's worth of dings, cracks, and nicks. The shiny "as new" models just don't seem as interesting.
PS. luckily, my wife also appreciates "lived in," instead of choosing a younger, more handsome, man.
