Cinch was the Insignia debacle but they went and collected it, refunded my money plus the £250 I'd had to spend on it. Utter pain in the hole. Ended up buying a Kia from Dickson's in Inverness as was north at time.
I think unless you know what you're looking at with a car or have a diagnostics for any model you fancy it's pot luck. I've had particular bad luck but so far the Kia is doing fine. But MOT is due soon
