I always suggest the purchase of extended warranties from the manufactuer of the vehicle, rather then these other companies that promise to be cheaper.
Never had any use for them except for warranty work. I do, and continue to do, all my own repair work on all my vehicles....
The only time anything I have ever owned has seen the inside of a dealer's shop was for recalls....
Still get about 3 postcards a week proclaiming "my warranty is about to expire". My warranty has been expired for over 3 years!
