I saved $3,400 through my advisor Tony.

I saved $3,400 through my advisor Tony. The same day I brought it in he called me to give him whatever information I had on an extended warranty. I located it and called it in to him. Within minutes he called me back and told me the deal was done - I pay the $100 deductible, the insurance company pays the rest. Two days later I drove off a happy man.
