Fair Market Price For Used OEM 20" Style 87 Rims?

[Weebie]

I was just wondering, what would be a fair market price for a set of used OEM 20" Style 87 rims? They do not come with tires so the price is just for rims only. The rims are in perfect like-new condition. These are original rims that came off a 4.6is so they are not replicas.

I know they cost a lot brand new but how much do they usually go for used because I have no idea. I might be able to get my hands on a set of used ones but the potential seller wants $2000 for them with no tires. He said they are over $4000 brand new. I don't wanna get ripped off but is his asking price reasonable with no tires? How much would you guys pay? I have seen the rims in person and they are in very good condition.
