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.
Beautiful truck

The guy I worked the deal with, his name is Bryant and
The guy I worked the deal with, his name is Bryant and made me feel welcomed. And as someone who normally had either boring or forgetful dealer experiences. I felt a connection on a personal level like we had known each other for a long time but we just met. We like the same music and he made me laugh. I felt he provided a experience that I would only experience at 1 out of every 500 dealerships. I plan to see him again.
Never had one. Always wanted one and love it.
I love my Denali. Beautiful truck inside out. When I drive down the road all heads turn. I couldn't have made a better choice. That's Cortez for you good service.

Service tech was friendly and got me in even though I didn?t have an appointment. The wait wasn?t long and the price was reasonable. I will be coming back from now for service on my truck. Great atmosphere, friendly staff and fast reliable service.
Early to tell truck has less than 100 miles
Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

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!

My lease was up on a few months and this particular
My lease was up on a few months and this particular morning when I was driving to work there was a loud grinding noise coming from under my truck. So, I called Ashley in service and told her I would be bringing my truck in this afternoon. As always she greeted me with a big smile. When I explained the issue and about my lease being up soon, she introduced me to Adrian. From that moment he had everything under control. He asked me what I was looking for and what I was willing to pay. He spoke to a service writer, came out with numbers I was happy with, showed me a truck I asked for and the deal was done! Adrian went above and beyond. from the storage boxes under the rear seats to the safe in the center console. He even cut off my trailer hitch lock on Saturday for me. I Adrian and Ashley a 10+!!! GREAT JOB!

Shop smarter Not Harder
To me these reviews all sound like everyone wants what they want this is a business that’s selling used cars a tip to help new buyers. You are given a 500 mile or 15 day warranty take the car you buy down to the original dealership or any mechanic have them do a over all inspection if anything is wrong with the car that the warranty covers take it back to the place you bought it from and they are legally obligated to fix it at their expense not yours because it falls under the warranty also make sure you buy GAP INSURANCE AND ANY OTHER EXTENDED WARRANTIES REMEMBER THIS IS YOUR MONEY AND INVESTMENT!!!!! Hope that helps anyone out on here or anyone looking for a car. I AM NOT A LAWYER & THIS INFORMATION IS BASED ON A PERSONAL EXPERIENCE…..
