Has anyone dealt with any of the following online warranty sellers?
They all state that they are selling the genuine Chrysler Factory extended warranty, and NOT a third party policy. The pricing is extremely favorable compared to my local dealer, about 47% cheaper to be exact. Your comments are appreciated.
