Warranties - true cost?

[CaptainSensib1e]

I need to buy a new car for the missus and have my eye on a nice Ford focus. The dealer offers a 12 month rac warranty for 350 quid but I have no doubt it costs them much less. I was going to ask them to include it as part of the deal but would.be helpful to know what it actually costs them before their mark up/commission. Thanks.

Great, thanks.
