Five Start Problem Solver GM Chris Powell!
We purchased a new 2021 Q7 from Audi North Scottsdale and were residing in New Mexico at the time. New Mexico is notoriously slow at governmental things (titling vehicles for example) and after almost a year and a subsequent move from Santa Fe to The Boulders in North Scottsdale we had a nightmare on our hands trying to get a title transfer. Chris Powell, GM, and his team stepped in and got the issue solved for us. We will always buy our cars from Chris!

Early in 2025 (11 months ago) I wrote a lengthy review of Berge on Google and now when I try to update it, it does not give me the "post" option again so I am putting the January 29, 2026 update here. Updated Jan. 29, 2026: I really enjoyed my 2025 Crown Signia Limited, but I decided I wanted a vehicle that was a little higher for ease of exit and entrance - I'm not getting any younger....so today I went back to visit Ernie Beler at Berge and decided to purchase one of the new 2026 RAV4's since they have a new attractive design, are slightly higher and are getting excellent gas mileage! I worked with Ernie and the "team" and ended up with a good solution! Thank You Ernie, John, Enrique, Scott, & Jeffery for treating me like "one of the family". My new vehicle is en route from Japan and I should be driving it within 2 weeks! I have referred a number of people to Berge and one of my last referrals resulted in Ernie selling a new 2025 RAV 4 to my snowbird neighbors from Iowa. They also tried working with a local Toyota dealership in Iowa but they found Ernie and Berge to be much easier to work with and Ernie was able to find just the right vehicle for them! They were quite happy with their experience and shared their pleasure with me. Need I say more??? This is a TOP notch dealership and their goal is to have many happy customers.
Nicest, best performing truck I've ever owned
My truck has a great appearance, inside and out. It is a pleasure to drive; and rides and performs great. It is the best truck I've ever owned.

I had never financed a car before and often heard of
I had never financed a car before and often heard of shady dealers taking advantage of people in need of a car. Unsurprisingly I was anxious about shopping for a car – particularly since mine was unsafe to drive and I had to rely completely on Miracle Motors to take care of me. The actual shopping experience was completely at odds with my expectations; Miracle Motors gave me an amazing first experience with shopping a car through a dealer. Affording the car was my #1 priority, and Travis the company founder listened to my financial needs and worked hard to match me with a loan that fit my needs instead of pushing me towards something predatory. We were occasionally interrupted by other members of his team due to how busy the showroom was, and I observed that the level of care I was treated with extended to all of their customers. Between Travis’s attention to my needs and the solid advice given by one of his salesmen Javier, I felt appreciated and at ease with financing a car through Miracle Motors. I would seek them out again in an instant the next time I need a car.

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.

CHRIS and marcio were incredible.
CHRIS and marcio were incredible. Their service is beyond beyond even though I didn’t buy the car. It was not because of anything they did, it’s just when I factored in the transportation to the northeast it just didn’t make any sense if I lived within 500 miles of them I would buy from them all the time they are the best of the best whoever trained them also should be commended Joe ct Former new car dealer for 50 years

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.

Donna was very helpful.
Donna was very helpful. She showed me a van that I was interested in. And then I decided I wanted to see a second one and she went out and found it for me. She is very knowledgeable about the vehicles I wanted to know about and suggested she could help me in the future because I did not find anything yet.

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
