Has anyone actually bought a car from one of these TikTok/Facebook "bank repossessed vehicle" sellers?

They advertise vehicles at very low prices, offer delivery or collection, and ask for a reservation/deposit before giving the warehouse address.

I'm not looking to accuse anyone of being a scam—I just genuinely want to know if anyone has successfully bought from one of these companies.

If you have, which company was it, how did the process work, and would you recommend them?

Equally, if you've had a bad experience, I'd appreciate hearing about that too.
