Rick Hawkins and Red’s are the best.
Rick Hawkins is excellent. Straightforward, opposite of a stereotypical car salesman. Pleasure doing business with these folks. Will Patronize again in the future thanks much.
Most like new used car have ever purchased
Unbelievable how clean this used car is. If you didn’t know different, you would think is brand new! Very friendly staff! Wonderful purchase experience. Definitely recommend! Quick and easy purchase experience. No haggle. Used car was immaculate...looks brand new! Husband very excited for his new toy.

Ask for Rick
Helped a friend pick out and buy a truck at Red’s Auto & Truck. We worked with Rick Hawkins and he was refreshingly knowledgeable, professional, and polite.
My Favorite Truck
Lane Departure saved me on a few long trips. Seats are extremely comfortable. Fifth Wheel Prep made it extremely easy for my hitch installation. Amazing Sound System

Greg Wolaver was a great help in regards to my long distance purchase of a used Jeep Commander. He was up front during the whole process and greatly assisted in the shipping process. I haven’t gotten my vehicle yet but if it’s half as good as he stated it will be a great purchase.
An overall nice truck but for a person at my size(5,11)
An overall nice truck but for a person at my size(5,11) the mirrors and posts really block the view. My tinted windows really amplify the problem. The hood also takes a bit of room for a short person. Its a comfortable ride and works well in my line of work in excavation. The sound muffler in the hood makes you think something is wrong but apparently its not.

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.
Duramax is king
GM truck interior too small, drive train is very dependable. Fast like the sports car of trucks with independent front suspension.

2024 GMC 3500HD AT4
This review is for a two week old truck. I have been trying to get a 3500HD AT4, gas engine, 8 foot bed, 5th wheel prep, in blue for over a year (almost 2). My dealer finally received an allocation and I was off for the build!! However, when my build order was sent to me the color had defaulted to black (blue was discontinued for 2024) and the only way to change it was to cancel and start over.....so black it is!! The truck is gorgeous and much larger than I thought! I am pleased with both exterior styling and the 2024 interior refesh. My only complaint is the seats, they are a bit firm.....still comfy....but firm. The GM sunroof is small, so small I passed on the option. Mechanically this truck is a pretty sound design. Another 50hp for the 6.6L gas engine would be nice, but 401hp is pretty decent. A PTO offering in the up level trims would be nice, as would a larger/dual fuel tank option is needed (GM is the only one that doesn't offer one), and a factory level in the front, and while I am dreaming a front locking differential. GM could up thier paint game, when approaching 90k I expect better paint. Value wise it is as good if not better than the rest of the over priced trucks on the market. Rumor is 20K per unit on average goes to the UAW pension, that's why your 50k truck costs 70k. In closing I have zero regrets other than the color, but I needed it immediately so here I am.

An excellent experience all around.
An excellent experience all around. The sales person was fabulous. Now the downsides: (1) From the purchase quote to finance ... like most dealers, a long list of add-ins one would have though were included in the quote; and (2) the car itself has a major, serious issue. I suspect there will be some serious accidents in the future forcing GMC to address the matter.
If owned Three Avalanche
It is a strong reliable truck and I would likae to have one for myself as a work truck and hauling heavy equipment like a man lift and compressor and still do some light duty work

Joey was great service manager...car service correct and prompt...very positive experience. Car was returned clean and with a full service report. Highly recommend dealership.
Great Diesel truck when emission sensors work
Great vehicle for pulling my fifth wheel RV which weighs around 20,000 pounds. This dually truck pulls the RV very nicely without any significant strain on the engine or the transmission. However, like all of today's diesel engines there are 4 different system of emissions on this truck. Each one of these emission systems has sensors associated with them. If one of these sensors goes bad the truck will not perform optimally and sometimes it will go into the limp mode. Unfortunately this is not unique to GMC trucks. All manufacturers are battling this system. Also, I have had to take the truck to the dealer for computer upgrades in order to improve performance. I wish these upgrades could be performed on line (through wifi or with my own phone service). It sure would make things a lot simpler and improve the through put of the dealers who are already strained because of the limited number of available diesel mechanics.

Fantastic people, the process was so easy and stress
Fantastic people, the process was so easy and stress free…I just stopped by on a Saturday over the 4th of July weekend just to look at a Hummer ev (I planned on Buying another Hummer I found online) and I left the dealership 3 hours later with a new car and new friends…I dealt with Charlie and Ryan, from the second I stepped on property and met the guys for the first time I felt like I had know them for years…I am a great judge of Character and there easy going positive personalities where very genuine and so authentic, it made me and my wife feel as if we where dealing with a good friend or family member that had our best interests in mind. From start to finish and even 3 months later I am still feeling the warmth from them. I will never buy another car from another dealership as long as Ryan and Charlie are there…AutoNation is Lucky to have them on there team and I am reminded of my experience every day I get into my new Hummer EV and I will continue to pass the good word on to everyone I encounter!!! Thanks Alpine Buick GMC
