Anyone have an experience of buying car warranty’s ?

I’m looking to get a new (second hand) car in the next few days and I keep being told I have to have this AA warranty they all seem to be pushing ?
I’ve done a bit of searching round and found that the price being quoted is way over the top compared what’s on the net. I’m being told that 12 months is £395 where I’ve just found better cover for £180 (http://www.warrantydirect.co.uk/ ).
Anyone have/used these and can tell me if they’re any good ? Do they really pay up, or, like most insurance, try to wriggle out of it ??
