Yer but not sure where you are-----if you are in BKK then there are lots, with the pandemic they also morphed into doing internet auctions---which I dont know anything about. At the last auction I went to (5 years ago) we had to pay 10K to bid---returned if you dont buy.
You 100% need a Thai with you -no matter how good your Thai is, it goes at speed. So tell them to bid in lots of 5K and tell your Thai person what your top price is.
I got a 7 month old 4 door Mazda (6 years ago) at 320K to have it that new the guy must have stopped paying the minute he drove out of the dealers.
Drawbacks are that you dont get to drive them----up here there all in a big field & you can inspect them as much as you like from about a week before the Auction--but you only hear it running as they drive it up to the bidding plate. That last one my Daughter brought was jerky and missing a lot.
We found out after that latter it was just a minor electrical fault ....... dont know how that happened....................
