This was probably the easiest transaction I've ever done. I called Knapp on Friday evening and talked to Ryan about an Extended Warranty. I don't think we were on the phone ten minutes and I had my questions answered, got a quote, and received an email with a sample contract and a brochure comparing the two plans. I called Ryan back on Monday afternoon, and again no more than ten minutes on the phone and I had bought and paid for my new warranty, Also, the price and the features were top notch

I've looked at what the competition had to offer and quite frankly, there is no competition. Ryan is very knowledgeable about the products that he offers. All in all a great experience.

I shopped around the Internet for a GM extended warranty for our SRX. Not only was Nate very helpful and informative, his pricing was much lower than my local dealer. DEFINITELY recommend Knapp Motors!!!!

Great communication. Smooth transaction. They're in Michigan and I'm in southern West Virginia. Everything was handled through email and phone conversation. Larry Wahl was extremely nice and easy to work with. Chad Loar sent the paperwork for my signature and answered any questions I had. I'm completely satisfied.

Found the GMC Protection Plan at Knapp Vehicle Service Contracts online. I was pleasantly surprised by their no pressure service and excellent pricing.

At the GMC dealership where I purchased the vehicle they tried to sell me a non-GMC protection plan for about $1850 MORE than I ended up paying at Knapp. And the warranty at the dealership was not for as many years and miles than the Platinum GMC plan I purchased from Knapp.

I shopped around and they gave me the best price for my car's extended contract and most importantly I got a real GM extended warranty, not some aftermarket junk that half the dealerships won't take or they'll make every excuse for why a part isn't covered. With a GM extended warranty I know I'm covered at any GM dealership.
