You're going to love it and it sounds like you got a good price also! If your rear end don't agree with the seat, you could always resell it and still break even. Good Luck
I bought a used heated Corbin on eBay and I love it! Seller said he put over 20,000 miles on it. But the seat is still very firm. I didn't think I needed the heat option but I'm glad I got it.
