I don't think it was ignored, it looks like it has CalTracs on it. So it may have just been set that low.
It looks like there has been A LOT of work done, so it would definitely be important to assess the quality of that work. Looks like the whole floor pan was replaced, connectors added, lower quarters replaced, etc.
And of course just the fact that there's an actual photo album with pictures on film says it's gotta be like a 20 year old restoration. It does look like it was a well documented job though
P.S. maybe it's different in other countries/states but here all of those "hot rod car sales" places are insanely overpriced and the cars are usually a pretty paint job over junk
I think they're all horribly overpriced. As for the quality I think that varies a lot, the issue is that the dealerships don't usually know anything about the cars. A lot of them are on consignment, so that's where the high prices come from. The owner asks what they want and then the fee goes on top and they all end up being 15-20% too high. But the quality just depends on the owner, although if you're taking it to a consignment shop it's probably because it isn't selling easily so there tends to be something "wrong" with them.
