Car appreciation... the aesthetics, the engineering, etc

I can see why you'd say that but everything else checks out and everything else about the car is good. My instinct says he's straight up, but he might genuinely think it just needs a re-gas when it doesn't.

Just checked and there's an ATS Euromaster where he lives so I might suggest he goes to get it done as I'm nervous it might not be a re-gas that's needed and I don't knock the £50 off. He doesn't want to sell it till Tuesday so he's got time...
