Laura Buick GMC review
As always the experience at Laura Buick GMC was excellent and we could not be happier with the vehicle we purchased. The entire team starting with our sales person went above and beyond to make sure we ended up with the vehicle we wanted at the best price possible. We have bought multiple vehicles from Laura Buick GMC and will continue to buy from them in the future.

Fort Collins Dodge, Chrysler, Jeep, RAM review
The most important element of this dealership was the salesman. Joe Zielonko was super knowledgeable and a great fellow to work with. In my 6 decades of purchasing cars, Joe is in the top 5 percent. We felt very comfortable with Joe and we did not feel pressured. He listened very well to our needs. He is a credit to the organization.

CarMax Palmdale review
Recently I had to get a newer car and believe me I was stressed because of the situation but when I went to CarMax which this is my second car from them it was once again amazing to work with them! I had the pleasure of working with 2 amazing sales associates. Helen Mayo who was my main sales associate and Cheyeene Toliver who helped out my wife and myself when Helen was off! They both were very kind and helpful and made the process an ease! I was thinking of other options but since they were amazing I went with them instead if your looking for a car I highly recommend you ask for either of these two women they are a great help!

Juwal, Travis and financing or seamless and didn’t harass us to add add-ons because I told what my budget was upfront and when I needed the car to do and they found that car and they made it fit my budget and I’m talking about cash budget out the door cause I don’t do car payments They are lovely lovely people they’ve called to check on the car and me and my daughter because we need the car for the safety features because of our medical issues this dealership treats you as though you are family which is greatly appreciated in a really cruel world.

2020 GMC Sierra 3500 review
The Texas Edition combined with the X31 package and premium SLT makes a very nice combination. The Sierra 3500HD gives you a luxury interior and ride with all the capabilities of a great pulling truck. The Duramax is quiet yet powerful. It is no doubt the best of trucks for 2020.

Miller Buick GMCReviews
2020 GMC Sierra 3500 review
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.
