The OH persuaded me to part with lots of cash when we bought our car for an extended warranty from Swann Insurance. I didn't want to due to past bad experience with this sort of thing in the UK (nothing being covered, impossible to claim etc); but, as those who know me will appreciate, I try to keep OH happy all the time so we spent the cash!
Anyway the worst happened and our central locking system went on the car! I gave the insurers a call about who to take it to and they said "anybody you like!". So we called our local Devonport mechanics who suggested a company called Milford Auto Electrical in Wairau Park. Phoned them up and took the car to them the next day.
On Tuesday night I received a message from the company saying that the central locking was fixed (and Swann were happy to cover the cost) but there were worse problems and the whole computer needed to be replaced. So another call from them to Swann the next day and they got on with replacing the computer.
Anyway, the long and short of it is that the car's electicals work perfectly now (so to Milford Auto), Swann Insurance have covered the lot without me having to make a claim and talk to anyway myself as the electicians do all of that directly (so to them), and the total cost of the repairs come to more than the cost of the warranty with another 2 years to run on it (so to OH!).
So if you are thinking of getting an extended warranty with your car I can say that, for these guys at least, it is easy to claim and they pay out without a fuss!
