I've bought 3 cars off of ebay, sight-unseen, and paid for them. 2 were not running cars and I did not have a lot tied up in them. In each case, I wrote the sellers before bidding and asked a few questions and got addresses. I looked on Google maps and zoomed in on the addresses to see where they were located; one was at an auto shop and another at what was a home in a good area with a big barn, so I figured they were good to honor the deal. They did.
