Buick Enclave Premium
It was worth the 2 hour drive to have a great buying experience!
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.

Excellent service
We have bought our last two cars here and the cars are great. One from the show room and the other was slightly used. Thier service department is very friendly and gets you in within reasonable time. If they get a cancelation, I get a call to see if I want that slot. I have Hirning service all my vehicles.

Great luxury ride with great pulling capabilities.
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.

Don't be fooled by just low prices - they all pay the same for vehicles. These guys know how to order new trucks with the right packages that won't cost you an extra arm and a leg. Save thousands by knowing how to order the right option packages on your next vehicle. Some dealers don't know how and you either get a truck with too many stupid options or not enough.

AWESOME Team!
AWESOME Team!! Service to Sales. On our trip to Mt Baker with the entire family loaded for a full day on the mountain, our 2021 GMC Yukon XL AT4 broke down on i5. Blade Chevrolet was the closest dealership to us. We snagged an Enterprise rental from down the street and left our GMC at Blade Chevy for repairs, this would be our first experience here, and will not be our last. As a former Service Director in Retail I was had the pleasure of working with Jason, Certified Service Advisor. Jason and his team of advisors and technicans were knowledgable, polished, guest focused, while ensuring the highest level of care was provided. We had our truck back in our hands by. Thursday that week, Blade Chevy has earned my Loyalty! Thank you Jason, and the entire Service Dept!

Great service by salesperson(s). I have never like the ?I?ll check with the boss routine but I guess that is to be expected. Jody was very knowledgeable and cooperative and went out of his way to show us models.

I was very pleased with my experience with Impex
I was very pleased with my experience with Impex Chevrolet. I found the vehicle on line and was able to put a down payment on it also on line. I made arrangements to drive 3 hours to the dealership from my home in Virginia, and met with Marqus Brooks, the salesman handling my sale. He was very courteous and professional. He was able to explain different options available to me regarding extended warranty, and assisted in completing the sale. Since I didn’t have a trade in, I was able to put a sizable down payment and financed the balance. The truck was freshly washed, and had a full tank of gas. I appreciated doing business with them, and would do it again in the future.
