It just depends. Ebay is not what it used to be for sellers with the constantly rising fees and restrictions, and that thins the herd of merchandise available. I am noticing a LOT less selection of the vehicles I browse this year.
Ebay used to be a fantastic place for used 911s, even with the obvious crap factor of many of them. Still, there were lots of great cars/deals which is more than I can say for any of the SoCal used Porsche lots which are all junkyards.
I've won at least 3 vehicle auctions where I did not complete the deal because when I arrived to pay for the car it was a POS. All 3 times the seller let me off w/o a hitch, ie. no $$ of mine kept or bad feedback left. They knew what they had. I bought my truck on eBay and it was exactly as represented.
There are legitimate steals on eBay from time to time, but you have to be quick with the "buy it now" button when they happen. Last fall I lost out on a 2005 truck that was *exactly* what I want, (and not very common), for ~$6k under market value. While I was on the phone with the bank, someone else hit BIN button and I'm still crying over it. I could have flipped it for the $6g the next day if I decided I couldn't afford it. And BTW, it was showroom perfect w/ 50k miles of factory warrantee left. (Diesel).
