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.

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.

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.

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.

Service here was amazing!
Service here was amazing! They aren’t pushy while you’re looking around, but are super helpful and responsive when you have any questions. I personally worked with Eric while purchasing my car and he was awesome answering the many questions I had throughout the process (thank you Eric!). Overall a great experience and I’d recommend them to anyone looking for a car! :)

Gregory Experience
Had a great experience at Camelbackford Greg was very helpful and knowledgeable, experience was fast and easy I highly recommend you coming to buy a car from Greg!
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.

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 (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!

2020 GMC 2500 AT4
This truck is the truck that all others should look up to. It rides great, will tow a house, runs smooth, and gets great fuel economy. The Allison transmission is so smooth. The AT4 looks great too.

It was worth the drive!
My husband and I picked up our new 2022 Mazda 3 yesterday. We live in Green Valley but could not find the car we wanted closer than Scottsdale. We dealt with Austin Mougel by email and texts to trade our vehicle and buy the Mazda we wanted. We could not be more pleased with the pleasant, careful and thorough process completed by Austin and the rest of the Mark Mazda team.
