Don't do it!! We purchased a Suburban from them in August 2015, with an extended warranty. I was told at the time of purchase that it was the best they had. I called today to find out which plan exactly and was told they didn't know. For $2000 you can't tell me which plan it was!? I need to call the number on the pamphlet!
Furthermore, the guy who did the financing told me we needed an additional $300-$500 cash to put down on the vehicle for financing. The money went to his pocket because there is no record of it going to the finance company or on my paperwork!
So yourself a favor, stay very far away!!
