i have a nationwide flexplus account which has breakdown cover with brittania. i had a wheelbearing faliure on my trailer on the m25. it was a big trailer and loaded with a car. it took several hours to even get a van to me, he then took the wheel off and we limped to the services. a hour or so later 2 recovery lorrys turned up, one to take the trailer and one for the car that was on it. the car made it home that evening the trailer took 2 weeks. not a perfect experience, but it was a difficult recovery as the trailer is right at the max length for recovery. the reason it took so long to get the trailer home was they where trying to find the parts to repair it so they could tow it to me instead of flatbeddimg it back. problem is the parts are hard to get.(infact i ordered them 3 weeks ago, still havent got them.)
however, still a better experience than the rac, and it was their subcontractor that let them down, not brittania themselves, who where going spare trying to g et recovery to me(snow)
