Century Ultra Cap price?

Was randomly on CL, and found a listing for what looks like a Century Ultra, one sliding window, one flip up, listing says there's "a light" that can be wired up, supposedly in mint condition except one of the locks seems to be seized. Guy is asking $500, seems pretty cheap to me, but I have 0 idea what these things sell for. Only downer is it's color matched for a dark metallic grey, and my truck is black, but for $500...

Edit: Sorry this would be for a gen 2 long bed.

 

Century Ultra is a Leer 100r with different badges on it. There should be a slightly bigger market of used Leers out there, which would hopefully help you narrow down the price.

But yes, 500 is pretty cheap. Probably around 2500 new.
