“I’d like to thank you for a non-stressful car buying experience.  I appreciate that you didn’t do any “hard sell” sales tactics.  You were honest and very upfront with me during our whole encounter.  You handled the paperwork very efficiently, minimizing the time needed to complete the transaction.  Also I felt you offered a very fair amount for my trade-in.

I would certainly recommend you to anyone in the market for a different vehicle.  Love my Ford Escape!”
Thank you,

“Just purchased an 01 Chevrolet Suburban from Doug Dyer today. Extremely pleased with how helpful Doug was. I had never purchased a vehicle from a dealership or gone through the financing and trade in process. Doug took the extra time and effort to walk me through everything. He understood my family’s needs and credit situation and made sure I got the vehicle that was right for me. I never expected to have such a great experience. I will definitely be checking Sullivan Auto Center for any future pre owned purchases! Thanks again Doug!”
