Offensive to sellers but have people gone over the cliff on Car values

Same car. Had it appraised a few years ago. It’s a factory 360hp car. Repaint in 1999. The guy doing the appraisal said: too bad it’s a 75, even though it’s totally original it’s not worth any more than 1 that has had body panels replaced or 100,000 miles on it with a lot of stuff replaced. I was kinda shocked to find out a 318 beater that was restored half assed was appraised more than mine cause the guy had receipts for the work done to it. He didn’t even do it himself. Kim

I have a 76 Pontiac Ventura that currently has 38k miles on it. Bought it with 27k miles in 2011, had not moved from 1993 to 2011 when I got it. Had to go through pretty much everything, brakes, exhaust, fuel system, all hoses and belts, rad was plugged, changed all fluids, rebuilt carb, flushed fuel tank, replaced brake lines, calipers, wheel cylinders, hoses, new fuel pump, etc. Still had the original tires on it, rock hard BFG radials, spare has never been used. Had it repainted in 2016, otherwise all original, appraised for a good chunk more than I expected, but not a high demand car. Now if it was a Nova, probably be a different story.
