End of car leases - What to do?

[OAS]

I just went through two car sales with my son on ebay. What a disaster. One that sold the winning bidder now wants to make payments. The second didn't sell at the reserve price but we got an email from a guy in Vermont that made a reasonable offer but we waited 3 weeks to get his check. Plus ebay wants to charge me a percentage of the sale and neither one sold, cash in hand from the bidders.
