The one I saw recently was that Matt Allwright, I can’t recall the exact program, and it was a white van. About £4K which was about £3-4K too cheap but the punters thought they were getting a bargain.
One guy travelled about 5 hrs or so to turn up at a random address and he was met with the “oh no not another one” statement.
What amazed and astonished me was that he, and two others iirc paid in full before seeing/going to collect the vehicle.
The other unbelievable thing was two of them acknowledged that they knew it was too cheap but still proceeded to make full payment
I’m sitting there on my own actually speaking to my TV saying WTF, surely there’s not one person stupid enough to do that never mind three!!!
The deposit one seems to be the more common scam according to that TV show
