AlvinC answered a question about my Ford truck that only someone with an in-depth knowledge of his subject would have known what was going on.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I needed help with my car on Saturday morning....got a response in 5 minutes, and it was the perfect solution. Thanks again to your service.

BRNew Jersey
