Weber Ford review
Luke made the process pretty easy.
Luke made the process pretty easy. Made a deal, signed the papers, drove the new (to me) car home. No hard sells on any of the dealer add ons, etc. Even got me another half percent off the rate I already had from my CU.

Roger Jennings Inc. review
New Tahoe
I traded my beloved 2014 Silverado in for a gorgeous, loaded 2016 Tahoe. Thank you Josh, Kenny, & Kelly for running the dealership the way you do. We were most likely going to buy a Lincoln until Kenny presented us with the deal of a lifetime. What was I thinking?? Josh *almost* missed out because he thought he needed a vacation. You now have customers for life, which is nothing new, but please stay away from my bank account for a few years. Thanks!!!

Laura Buick GMC review
Overall good drove over three hours to arrive, pain that
Overall good drove over three hours to arrive, pain that policy is they don?t accept checks or certified checks when purchasing outright. Did money transfer before leaving home and waited an hour at dealership for verification of transfer total four hours (ridicules). Other than that process was simple enough.
