<I have seen paint job as good as new cars. It's rare and
very expensive.>

I've owned 3 such cars. One was a Corvette that had been repainted from silver to metallic brown, total color change and virtually impossible to detect. Don't know the cost, bought it that way. Second was a '67 Ford Mustang, also bought after the paint job, but had the receipt for $4,500.00 (back in 1994). Third was a Chevy van that I had repainted, and I'm not kidding here, it was done at a Maaco. I went in for the advertised $189.00 special and was talked into spending $800.00-this was in 1986. I was amazed when I picked it up-it was flawless. Couldn't get a paint job like that today even close for that amount. FWIW, Maaco's are franchised, and that one had just been taken over by a Korean family, and damn, they did a fine job.    Jeff
