Once sold a mate an Alfa Romeo with 85k on the clock…..
I can’t remember the mileage but it was probably similar when I did this too.
It didn’t go well (the car).
He’d been after it for ages and said if I didn’t get what I wanted on eBay then he had an offer on the table.
It went for more on eBay, twice, but, well, eBay innit? Buyers started coming up with complications and delays and eventually dropped off the radar so I sold it to my mate (work colleague as well) for a bit less than I wanted, but a reasonable price.
It was understood that it was a private sale, sold as seen, no warranty given or implied.
It was running great when I handed over the keys. He was delighted.
Later that very day, the engine began grumbling and losing power.
After some investigations and attempted remediation, he eventually got a recon engine fitted.
That turned out to be even worse than the one it replaced.
He must have spent more on it than he paid me for it before eventually damn near giving it to webuyanycar.
He never once asked me for a penny, and we remained good friends.
