Eh, he bought it, his problem, should have told him to feck off.
What was this minor problem?
He claimed the cylinder head gasket had gone because of the strange looking gunge in the header tank.
It was the 'K' Seal that i put in to stop a very slight occasional dripping from the radiator 7 years ago.
Even did a complete coolant change 3 years ago, and it still never started leaking again.
Total success and highly recommended btw.
I'd completely forgotten about it and therefore didn't mention it to him.
The car is 9 years old, and the tw@t is a complete and utter hysterical bell end that THINKS he knows everything, but in fact, he doesn't, as I've now proven to him.
His loss, my gain again.
Never deep down inside ever really wanted to sell it in the first place tbh.
Dunno why i did the deal now.
IF I'd known there was something radically wrong and wanted to be a lying deceitful bass turd, I'd have told him to cock off, and not given him his money back...well within my legal rights too. I've checked it all out.
