Willie was great to work with and made the buying process
Willie was great to work with and made the buying process very efficient. He was also very knowledgeable about the truck and did a nice tutorial to set it up and show me the features. Did the negotiation through email and when I came in to faint the paperwork I was only there for an hour and fifteen minutes total before driving off! The usual upsell of extras during the finance process but they weren?t too pushy about it.
Beautiful truck
I love my 2021 GMC Denali 2500HD. I have gotten more complements on this truck than any other vehicle that I have owned. I get great highway fuel milage average 19-26mpg,which is great for a heavy duty truck!

Easy and fast
Buying a vehicle is never fun, but Jordan at victory motors has been outstanding. From his honesty to his communication, he has made this process super simple! I promise you, they are great.
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

My first EV repair and the were great!! Dealer very NICE. Andrew advisor kept me informed and did alignment under warranty. great place to service or buy.
So far so good!
So far so good! This truck is the nicest truck I have ever driven. The stance, ride comfort and options are top notch. I went from a 2023 High Country that was having drive train issues but had all the creature comforts that you would expect in a top of the line truck. With the lack of confidence in that particular models 10 speed transmission issues, it became necessary to reestablish my confidence in my General Motors product.

Great Customer Service and Sales Team
They did a great job of helping me find the perfect pick up. Levi spent a lot of time helping me. A very good experience. After the sale, I had a small issue with the battery and they swapped it out for a new one, no questions asked. Great dealership!

Very pleased with the response I received from this dealership. I've been in contact with one salesman and we are still communicating with each other about one particular car.
Was my first car and will probably be my last
Very reliable tank of a truck. Has never failed on me and has continued to give perfect performance time and time again. Only wish I could have owned it sooner

This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

Mike is great worked with me and made the entire process quick and easy. Friendly and professional
Hardest working truck I’ve ever had.
The truck is a tank. Ask it to pull something...no problem. The only downside is gas mileage 12 mpg if your lucky. If your towing a heavy load down to 6-8 mpg. But sometimes you need a Tanaka and mine has reliable. 215,000 miles on it now and I wouldn’t think twice about driving it cross country towing a 30’ toyhauler.

Exceptional Service
My experience with Davidson Gebhardt Chevrolet was exceptional, to say the least. Having worked in the customer service industry for many years, I always anticipate and expect a great experience. With our current economy in the slumps, great customer service seems to be a thing of the past. But not at this dealership. Every employee I have encountered is happy and helpful. I have been using this dealership for a few years now to service my suburban. Recently, we had an unfortunate and costly mishap where all wiring and many modules had to be replaced. We filed a claim with insurance and Darek was my service advisor. From the very beginning, he was helpful, polite, professional and attentive where he would always check in with me to give complete and thorough updates about my vehicle. Darek was very knowledgeable with every little detail from filing supplemental insurance claims to answering my many questions and reassuring me that my suburban was in good hands with his technicians. Josh, the service manager, was also very helpful and knowledgeable with all things service and was able to provide a helping hand when needed while always being polite and professional. To the owner of this dealership, you truly have a wonderful service team. Working in the customer service industry for Hilton corporation, I understand this team positivity is due to the company structure and truly caring for your employees. So kudos to you and upper management for figuring this out and rewarding your team for a job well done. To any other potential customers considering servicing your vehicle through this dealership, I highly recommend them for any insurance claims that involve mechanical work or just a simple service appointment. The service department team will get it done, get it done fast and get it done right the first time while being thorough and upfront with all costs. Thanks again Davidson Gebhardt Chevrolet service team. Katie Martin
Very beautiful truck
This truck would help me thru out my needs I and my family love this beautiful truck, there is no better place for me to shop than the Paso Robles Chevrolet I highly recommend them

Customer service was great service department was great the only complaint that I have is when I have an appointment for 1:30 and it is two and a half hours later when they get finished do not understand why it takes that long when you have an appointment
Best truck I have owned
I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck is outstanding. The 6.6L gas engine actually gets great gas mileage. It gets about the same as my Ford f150 ecoboost. Probably better on the highway. Looking at about 13 miles in the city and 15 plus on the highway. Definitely got a better truck for the price compared to any other american models with the same characteristic and options.

I dealt personally w Manny Rodriguez. He was intelligent, knowledgeable, honest and transparent. I applaud MM Chevy for hiring such an inspiring young man. Would go back again in a heartbeat!! I purchased a nice Silverado due to Mannys professionalism! Phil Bravo
Great Truck
I paid over $106,000 for this truck with warranty. Do not care much about miles per gal. at that that price range. Just too much truck for me at my age.

Best Car Buying Experience EVER
I have bought a lot of vehicles in my life time but this was by far the easiest and most pleasurable car buying experience I have ever had. I sent an email to the dealership around 1:45pm to inquire about a car, drove to the dealership at 5:00pm and drove home at 7:30pm that same day. Ricky in sales was amazing, easy to deal with, I told him what I needed and he took care of it without a bat of an eye!! I will refer anyone to this dealership and specifically to Ricky Pim. Thank you guys!! you are the best! PS - Finance guy, equally as great!! Jersey!
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
