Questions for those who sell/have sold cars on ebay ...

I sold three cars on ebay. In each case I got a paypal deposit right away. (That way you know your not going to wait days or weeks for a deadbeat.) And then got cash for the balance when they picked the vehicles up.
I also had a guy once who claimed he was sending cash with his transporter, so I would be paid at time of pickup. Guess who never showed up, or ever got in touch again. If you keep the conditions of payment under your control, then you can make sure that you don't get ripped off. I think most buyers are legitimate, but you have to be careful to protect against the other ones.
I sold another car to a guy from out of state who wanted to write a check for the purchase. I said that's fine but I'm not releasing the car or the title until my bank says the funds are in my account. He was good with that, and the transaction went smoothly.
