Dishman Dodge RAM Chrysler Jeep review
Can't say enough good things about my experience buying my truck from them. It was a no pressure experience. Very nice people from the salesman to the finance guy. Both went the extra mile to make sure I felt good about my purchase. Very upfront with no surprises.

West Metro Buick GMC review
Best dealership around! The kindest staff, patient and willing to help you find exactly what you are looking for. Corey was super helpful and made the process and breeze. We have purchased 4 vehicles from West Metro and I know we will be back when we are ready for another.
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.

Rosedale Chevrolet review
Was very pleased with my experience with David Gil Carrillo. He was very courteous and knowledgeable. I was treated very fairly as far as my trade-in and the final offer. I would definitely buy another vehicle from them.
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.

Auto Town USAReviews
Auto Town USA review
I would give Jake and his team the highest marks possible for a used vehicle purchase from a dealership. I found a vehicle that met my needs that was in great condition at a fair price. I flew to Idaho from the mid-west US and drove it back 2000 miles without issue. They were very responsive to all my questions in the process of investigating the vehicle and they were very upfront about the condition of the vehicle. I looked at several other trucks on their lot while I was there and it appeared all of them were low mileage, rust free trucks in excellent condition. I would not hesitate to purchase another vehicle from them again and in fact I plan to do so in the next year or so.
