Anyone know roughly how much a middle of the road Mapfre type warranty would cost?

I suppose more to the point is; if a car dealer was supplying that type of warranty with a car, but the warranty was unnecessary as the car had a manufacturers warranty which could be extended, what would be an appropriate amount to look for off the price of the car?

As I'm sure the dealers prices would include the cost of the warranty, and if they don't have to give it surely there'd be flexibility to negotiate?
