The data's available ,got to be willing to crawl through the car on your own to verify. Or pay someone to do it for you. (if you don't like getting dirty)
I had some items done at CHP and was very pleased with the results. He comes across as a standup guy.
PLUS, who is to say changes are not made after the report....I've posted before, probably your safest bet if paying high dollar for a supposed classic is inquire about getting the car inspected NOW and splitting the cost----if mine was on the chopping block ,I'd accept that. Price is reasonable for piece of mind. Of course I would have nothing to hide.
A few years back I went to look at a drag car ( 68 Camaro) out of state--looked great in the pics plus he had video of the car making passes. Well the car looked and sounded tired to say the least when we got there. I got a hot head and was instantly , um, mad. ( I was with trailer and cash for this pos.) Got talked into watching the tapes by my family. Some reason this guy's feelings were hurt by my reaction in the garage. So...current video was of some hard launces at the track, told him if it was a horse I'd have it shot and walked out. (and somehow my wife stays with me LOL! )
Like I've said ,cannot imagine buying without personally inspecting the car. And researching claims. I'm curious how this plays out.
Mind you the price of that car was peanuts compared to what a numbers Z goes for
