This.
We had a car accident last year and with finances being tight preferred to buy an older cheap run around at £2500
Did lots of research, did all the "right" things and seller seemed older, well to do and in large fancy property.
Car broke down 5 days later and garage said it needed 4 figure sum repair.
Contacted seller politely if they'd take the car back - No response. Contacted seller again to ask if they'd give us a partial refund and take car back - No response.
Our options chase with a solicitor which after the time/money involved didn't seem financially worthwhile OR a friend offered for their husbands "friend" to visit the seller to get the money back which I'm gathering was in a threatening manner.
Neither options felt like something we'd like to proceed with.
In the end we took a car out on finance.
We sold it on Facebook for £800 after being totally honest and upfront about the car and situation and stating "sold as seen". A chap bought it who repairs cars and sells them on again.
He said we were the most honest Facebook seller he'd ever met in the years he'd been doing this, which I though was a bit sad that he was used to other people trying to rip him off.
So never again and we will chalk that up to experience.
Every time I drive past the guys fancy house (It's in central town location), I think who would rip off a young family who'd just been in a bad car accident. If he didn't want to give us all the money back he could have at least given us a partial refund.
Some people are just scum to be honest.
