I have trusted and used Henry Brown for repairs since purchasing the Tahoe from their CASA Grande, AZ store in 2009. First with Mike Meade and now with Lou. Both very professional, knowledgeable and helpful.

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!

Tom Anderson and the service department at Henry Brown
Tom Anderson and the service department at Henry Brown always do a stellar job for my Yukon. I've been going here 8 years and each time I receive friendly, thorough, and transparent assistance. Joe Stenz is stellar and makes getting my truck serviced a breeze. I was able to work with Wes recently while Joe was out, and I recieved the same help I've come to appreciate from Henry Brown which is a testament to how Tom runs his department. I highly recommend visiting Henry Brown for all your needs.

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.
