If it's nice, my house
. In all seriousness, you will get interest here, early S registry, and ebay. Be prepared for the following:
Pelican - knowledgeable buyers, picky with infomation gathering, somewhat nitpicky with the car, want a bargain
Early S - very knowledgeable buyers, very picky with info, very nitpicky with the car, will pay top dollar for the right one
Ebay - buyers range from extremely knowledgeable to idiots (more the latter), need basic info and make a lot of assumptions so you need to say everything to CYA, and transaction prices are random, you may get extreme top dollar and maybe surprisingly low. There was a day when it was always top dollar, but no more.
