I had a complete ball ache selling my car listed as a 99p start price auction and “spares and repairs” on ebay.
I think there is a lot of dodgy motor dealers with an automated search on cars sold as an auction and spares and repairs (i guess normal buyers wouldn’t be interested).
When i sold mine, three guys turned up in a BMW 5 Series and refused to leave my house for 3 hours whilst attempting to haggle the 2100 quid price they bought it for down to 1300 quid.
The guys who bought mine were setup as a “dealer” from a house in Luton. The car was listed as a “private sale” on autotrader 2 weeks later. ebay account was closed after they bought it and autotrader did nothing.
They had multiple ebay/paypal accounts too, as they had to shuffle the money around to actually pay me.
It would not surprise me in the slightest if it was some kind of scam.
