I had an outstanding experience with Henry Brown Buick
I had an outstanding experience with Henry Brown Buick GMC, specifically working with Rigo Ramirez. Rigo made the entire process completely seamless?I spent less than five minutes at the dealership because we had already come to a clear agreement over the phone. He was extremely transparent, didn?t play any games, and truly listened to what I was looking for. Not only did he find exactly the vehicle I wanted, but he also beat the pricing from five other dealerships I had been negotiating with. If you?re looking for a straightforward, honest, and efficient car-buying experience, I highly recommend Rigo and the team at Henry Brown Buick GMC. I would absolutely buy from them again in the future.
One very awesome vehicle.

I needed a tire repair, my advisor kept me informed on the progress, the waiting room was clean and comfortable and the wait time was short.
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.

From start to finish our experience at Arrowhead Lexus
From start to finish our experience at Arrowhead Lexus was cordial, thorough and fair. We were not rushed and every question was answered. Robert Plumley, a personable young man, was considerate and accommodated our timeline, our priorities with pricing and car pick up arrangements.

Easy.
Easy. Worked out great. Good price no pressure. So far so good. Don’t expect anything to go sideways but if it did, I think you would be taken care of within reason. I’d do it again.

I just purchased a 2014 Mustang from David. Excellent service, I'll defiantly buy from them again. David took the time to do a virtual walk around seeing how I live in Tucson, answered all of my questions. By far a smooth and easy transaction. I love my car!!!
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.

First I have to say that I am NOT a review leaving
First I have to say that I am NOT a review leaving person, with exception Of Lifted Trucks. In the last 6-7 years the only reviews I have written have been for this store....on with the story... I just purchased my 4th Truck from the Glendale store . This is the 4 truck in 6 six years. The staff does NOT get any better then these folks. From the warm and inviting welcomes to the store to the Superior Management. These are the best people around and I can't thank the enough. I am a customer for life. Thank all of you Sincerely Dan Hubbell

Very fast response to my inquiry.
Very fast response to my inquiry. They provided all information in a transparent manner. Ultimately we did not agree to make a deal but I would use this dealership in the future if they have a vehicle that I am interested in.
Great Truck (sans MPG)
Love everything about this Duramax Denali except the fuel mileage. 13-14 Mpg tops when not towing. Bought truck cause previous was stolen. Wish I still had my 6.2 High Country!
