Thanks for the replies guys. I'm still on the fence with this one and still haven't heard back from the dealership, I'll give them a ring in the morning if I don't hear back by the end of today.
@kenfowler3966 Yeah, that was my reasoning too tbh. From what I've read, the timing chain issue usually rears its ugly head at <50k miles, so the fact that this one is up to 88k miles and has FSH suggests that the issue might have been addressed. With that said, still waiting on a call back from the dealer so we'll see.
@Expatman Yeah, the tow bar was a bit of a concern considering it's only a 1.2 petrol. Not saying that's inherently a bad thing, but if it's towed heavier loads it might not be the healthiest of engines. I'm no mechanic though so I have no idea on the real towing capability of the car or the overall impact that might have had.
