What about Mercari? Looks a lot like eBay buy it now https://www.mercari.com/us/item/m35145155772/?ref=search_results
Hmm. Never heard of it. New site am guessing. Ebay does have the advantage of an established online presence (1996 I believe) and name recognition.
Mercari looks to be set up for clothing toys and household items. Only listings for Buick was found under toys.
I did find a automotive section under "other". From what I've found "Listings are free. A flat 10% selling fee is only charged when the sale completes." Sounds better than eBay but not much exposure yet. I guess the big thing is that there's an APP for your phone to make it easier and if no sale than no big deal
Same exact thing happened to me. My idiot customer decided to change addresses the day after i shipped it. He argued with me saying nobody ships items same day. Well i did. So i called ebay office to head off the idiot. So i talked with ebay representative and i had all proof of shipment and date it shipped. They said your fine, he should've updated his account. I say Thank you and ignore him. Then i get letter from ebay telling me item never arrived, so i send all proof of shipment, tracking number, and even inserted pic of receipt. And didn't they side with him. I was pissed so emptied my pay pal account and removed my listings. I had over 2000 positive fedback. Of course they sent me letters telling me that they froze my account until i pay the $320 back. Then they kicked me off. Get this..... i decided to google both addresses to see how far he moved to from original address, 2 miles. Sure as **** stinks he picked that up.
