Acquired a decent 'eye' for cars having done a couple of restorations and knowing body experts that have showed me what they know; BUT lol, those guys can be amazing what they see that I miss. Last fall when I was re-doing my truck getting a nice rust-free box from the SW with some dings and such, the body shop owner was looking it over as we talked about repainting it and I wasn't all that fussy since it is my daily. He pointed out some imperfections "See here and over there" he says. I'm looking where he says to look then says "Ya won't see them cuz you're at the wrong angle and and standing too tall". Sure enough change position and they were noticeable.I didn't even think of that, having forum members check it out for me. I'm not looking for a perfect car, so I don't need too experienced of an eye.
How do you determine the market value of a classic car. There are some price guides but those don't always tell the whole story.
I've gotten to know the guy well over the years just a great guy and he said come look at the '67 GTO he had in the shop partially stripped down to quiz me on the imperfections. It was fun and while I found several he pointed out a few more. The owner of the goat had spent a ton having another shop restore it a few years earlier doing a poor job.
Another thing to be aware of is cars have their favorite areas where they rust...like the GTO behind/under the rear window. Guys on the forum can tell you about this so if you're hunting for a particular car be so informed.
