Chris Edwards was great to work with!
Chris Edwards was great to work with! He was never pushy, very helpful, and easy to talk to. We appreciated how quickly he was able to move this normally daunting process along. If you stop by Troncalli, definitely ask for Chris Edwards!
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

All the employees were very helpful from the time we parked until we left with a new car for my wife. The sales rep let us look at the vehicles we liked instead of pushing us towards something else! My wife left with the car she wanted ,very enjoyable experience!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Upon inquiring about the vehicle. I received a prompt email that someone else had purchased the cat. I also received a follow-up email asking if the dealership could be of additional assistance.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

My salesman, Dave, was outstanding from the very beginning of the contact and sale. I believed he was honest and represented the company well. He and I agreed on a price over the phone, and I accepted it. Before the purchase was completed, I was engaged by another dealer with a lower price. However, I chose to stay with Dave because of his integrity and my belief that a deal is a deal.

Everything was fine except, of course the long wait time. However, this time when I got my truck back it had an unpleasant odor in it. I drove home with the windows down and then washed the floor mat and it's much better.

The customer service was great. I have tow complaints: 1. A 3% surcharge when using a credit card which everyone pays with. 2. The waiting room was freezing. I know it?s extremely hot outside but it was very uncomfortable in the waiting area.

I just want to say that I had a very professional customer service experience with Ryan Ramdass and wanted to write a review to express my gratitude. Ryan and I had an issue that we had to address and resolve over the phone and he handled it very professional and cautiously. I would recommend Ryan to anyone who is searching for their next Chevrolet! He is a top notch salesman in my book. I his straight forward and to the point and says it like it is and I appreciate that about him and our conversation. Ask for Ryan when you look to purchase your next car he will not let you down.
