First off we bought from another dealer, and were promised the moon with this car purchased, turned out it had bomb of an engine, with it's configuration. And it did what the previous dealer set it up to do, it blew after owning it for two weeks. We are incredibly luck to have harchelroads GM performance garage right here in town. We took our highly modified 06 GTO to Cody Jantz, not only did he explain what happened to our motor, but why it happened. So many things we're wrong, I felt defeated and stupid, he explained why it wasn't our fault, and started building a plan to move forward, he helped us speak with the powers at be, to secure finances to pay for all this work about to be done to fix our dream car. I feel as though everyone at this dealership is there to help, Cody Jantz explained things about our LS setup on a level we didn't feel stupid, and we could walk away with an understanding of the process, alot of choices were made for this case each time, he explained our choices, what we needed and why he suggested this course of action, so you there customer are in charge of your build, but it's really easy to make educated answers to things, we knew nothing about, but Cody was there for us every step of the way, never complained about our questions, always stayed in contact, involved us in every decision. We would highly recommend Harchelroads Chevrolet to anyone, customer service here is "your number one", thank you to Cody and the performance shop guys and gals; thanks for Sid for handling our issues and putting Cody at our finger tips. Buying a car, or servicing a high h.p. ride like we did, this is your spot.
