Read through my thread before you decide to go through with an automobile purchase on Ebay. -
Intelligent Ebay Buyer's Thread - Just don't pay $650 more than the "Buy it Now" price like some sucker did on a vehicle that I was bidding on.
With EBay's search tools, it's pretty easy to narrow your search down to a geographic area that is local to you. This will permit you to see the vehicles before placing your bid. Plus, since most auctions run for 7+ days, you should have plenty of time to view and test drive the vehicle. Also, as suggested, don't overlook the use of CarFax to pull some details on the car that you are interested in. Fortunately, the cars on Ebay have the VIN number listed, so running a CarFax report is quite easy.
