Anyone here has any experience with....

my ex and I sold his Porsche on Ebay a couple years ago. A local bidder made arrangements to go and test drive it (we were storing it in LA while we lived in DC) and then he paid via check. It was all pretty easy. I did go in and counter bid to drive the price up a bit and I was very leery of taking a check (my ex insisted and, in the end, it was his $10k to lose) but there were really no hassles. So, there's one experience.

Thanks for your input. What about the listing fee and the percentage that they charge once it sells?

I bought a Lincoln Navigator off eBay without seeing it in person first. Needless to say it came with a 100k extended warranty so I wasn't too concerned about not driving it first. Bought it from a private party and got a steal on it.
