*correct* units are coveted by people building high dollar cars and generally go for good money.
so then it's a monkey see, monkey do: i have something similar so it must be worth just as much. or even though mine is busted ***, it's still "rare" so it's worth a bundle.
a lot of people are pie in the sky about their pricing. somebody can ask 1200 but that don't mean they're getting it.
i will say for a nice set that are rebuilt/covered i wouldn't blink an eye at 1K plus with the price of upholstery these days.
