is any breakdown cover, which pay for the repair if the car breakdown?
i have checked the AA breakdown cover, which also provides cover repair cover, but when i read the term and condition, it say the car must have less than 100,000 mileage, but my car has done over 100,000 miles Does anyone know of any insurance company that pay for the car repair, if the car beakdown, and does not have any limitation on the mileage.
