Yeah, this generally will save people a fortune over time. It will cost you full whack if you do ever need to make the call but since I ditched my pretty unreliable first car I've called a breakdown service once in 23 years. Even then the car was at home so it wasn't exactly an emergency but it was my company car and we have a fleet policy with home start. Not that they were going to start the thing as the fuel rail had come loose! Got me a tow to the dealership though.
My MX5 does have breakdown cover bundled in free with the insurance. European coverage too and the insurance policy is <£150 for the year.
