5 Stars!
Great people, fantastic service. See Dante Trybalski in sales. Everyone is Very friendly. Can’t say enough about Dante and the dealership. Other dealerships don’t compare.
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 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.

My experience with Autoboom of Scottsdale.
The courtesy of all the employees from the salesman Blane to the excellent finance director Ryan, These people made it easy and worry free as i bought sight unseen from out of state.The owner Jeremy was very attentive to my needs. There vehicles are top notch and low mileage.I definitely recommend this company and will use them for further purchases.

Oil Change and more : )
I came in for an oil change and these guys helped with so much more! Henry Brown Buick GMC--your people have exceeded my expectations. I am going to keep bringing my business to this dealership. There was a situation and from the top down, Jeff Martin was a huge help, he turned me on to Shane Terry whom made sure everything was perfect; my repair adviser, Kyle Kinderknecht treated me as though I were a good family friend/valued customer. And Kyle Jackson was sitting next to Kyle Kinderknecht--he even got in on helping me when I wasn't his customer. This place treats us right--thank you all!

This was not a typical dealer experience. They made my purchase quick and painless. Not pushy and very direct answers. I'm pretty sure I met every employee. Their customer service was great. Pricing was transparent. Got a great deal. No hassle and was in and out.

Excellent New Car Purchase
We bought a new 2020 GMC Terrain from Bill Beaudry. He made the process incredibly easy, even with us living in Tucson. He did not pressure us to come in for a trade-in appraisal before giving us his best number. He promised to make us the best deal - and he definitely kept that promise (his numbers were several hundred less than any other dealership and THOUSANDS less than Tucson GM dealerships). We were in and out of the dealership in less than two hours total. Bill is extremely patient and answered all my crazy questions/concerns. He was even able to find a Terrain in a different color after I realized my fiancée NEEDED a white one. The finance representative was low-pressure and did not coerce us into any additional extended warranties, etc.

The team at Henry Brown is very exceptional.
The team at Henry Brown is very exceptional. Purchasing a vehicle from across the country is stressful but my salesman Mike Roberts made the whole process very comfortable. I have spoken to many salespeople throughout my search for a new truck and am very glad i was working with mike throughout the purchasing process. I recommend henry brown for any of your future auto purchases!
