Hi Rick,
I had a feeling the prices would be way over the top but such is life.
As for selling the seat, haven't you got something similar to a Gumtree website in your country?
People shy away from something if it is too cheap, I sell a lot of used motorcycle accessories on Gumtree here in Oz, I take good photos, give it a good positive write up and I put on a reasonably high price and the I come down when they start to bargain, I come down to the price I originally wanted and the buyer feels that they have scored a great deal by them negotiating it down, everyone goes away happy, it’s a win win.
That is a very nice seat in GREAT CONDITION.
