I've done many many eBay transactions, both buying & selling over the past 7 years - never had a problem ......... except for the Jimmy, but that was a 33/33/33 split of fault between myself, the seller, & eBay. Had the vehicle history report (eBay didn't have one at the time - this one was posted by the seller) been up, I never would have bought it - and had the seller been HONEST, there wouldn't have been a problem either. But I did manage to wrangle $300 & a new pair of tires out of the seller, which is better than I expected. After all that he left me a Negative, back when sellers could do that.
When I sell, I use strict guidelines, all available when you list an item: Paypal account only -all others cannot bid/buy, negative feedback forbidden to bid/buy, countries I don't ship to forbidden as well, unpaid item strikes forbidden to bid/buy.
For big/expensive items, I usually just use Craigslist. If someone wants what you have, they will find it no matter how far out of the area they are. There are a few searches that allow you to search Craigslist from coast to coast for a specific item.
You'll have to deal with endless phone calls from absolute morons at all hours of the night, but it's free. I don't get pissed anymore - that just fuels the fire. I just listen & laugh afterward & share with my buddies. I never leave to meet anyone - if they don't want to come here to buy, then they don't buy! If they try anything tricky .... well, lets just say this is the wrong neighborhood for that sort of thing.
But like was mentioned, you have a much bigger audience on eBay - so chances of selling are upped quite a bit. If I do decide to list a car or bike on there, my bidding/buying requirements usually weed out the riffraff. There was one time I listed a truck, and forgot to add my "Paypal account only" requirement ..... and the truck was promptly "sold" to someone in Germany who needed my social & bank info.
It is like a fleamarket, which is great for me. Stuff I would have either thrown away or been left piling up here in the house & barn, I sell and make a couple hunge a month on. 99% of my stuff is a Buy it Now - auctions rip me off most of the time. Except a couple times I've been shocked at how high a price got bid up. Too much of a gamble for me.
