Well.... I swung by the guys house and had a look.
As suspected above the problems around that rear hub are down to an impact with a kerb. The guy was upfront about this and showed me a pic of the damaged wheel (which was replaced since).
One of the rear doors has some rust starting along the bottom and also on the upper sill there is line (join) which is starting to rust. There is a scuff on the front bumper that would need paint to make me happy.
Engine was cold on arrival, on starting piston slap was evident and no smoke when revved. Oil looks clean as does coolant.
The car is SORN so a sneaky test drive was had on a twisty hilly B road. It drove surprisingly well, I was expecting alot of clunks and pulling to one side but it actually was ok. I struggled with the auto box - opening it up on the B road didn't provide the instant gratification of my gt4 but then that's auto boxes I guess.
The temperature held ok during the test drive and the brakes worked (which was good news). I did comment that the car was nearly out of petrol, however he thought there was half a tank in it which means that there could be a sender/gauge issue.
On return the engine sounded good - no piston slap.
I just left it that I would have a think about it and make an offer if interested. So for now I'm undecided.,,,,,
