Sure as hell the winning bidder at $14,505 has a big fat ZERO for feedback. Next highest bidder = 14 for feedback.
BIG problem with ebay is they let one person have multiple accounts. That person has one selling account with high feedback. AND a bunch of throwaway buying accounts with little or no feedback. Ebay owns paypal and they both side for the buyer, not the seller. Because, without buyers, there are no sellers.
I buy and sell a bunch of small low dollar items on ebay. When it comes to big ticket stuff, sorry no ebay for me. Too many scammers out there. As a seller, you also end up paying listing fees for high ticket items that often don't meet your reserve aka don't sell. Craigslist, Auto Trader, Car Soup, etc. is how I would sell a truck.
Anyway, keep us posted if the winning bidder actually paid and the delivery of sold truck went ok. We hope the best for you of course.
