Sara is the best!
Sara is the best! I highly recommend this dealership!! She kept me informed of the progress of my vehicle and explained all the work done. No surprises.
Great truck!
I bought my 2020 with 36k miles a couple of years ago and I now have 60k miles of trouble free very enjoyable driving. It was expensive, but worth every penny. The ride is so quiet and comfortable my wife and I prefer traveling in it instead of our 2018 Acura MDX which we also love. The 5.3 V8 has plenty of power and towing ability. The multi-function tail gate is genius, I hope to never be without one again. We so enjoy all the bells and whistles, especially the wireless phone charger. So glad I bought this truck!

My love my new Chrysler 300
I had a terrific experience at dodge chrysler jeep. Adam was my salesman very professional yet funny and knowledgeable! I love my new chrysler 300. Thank you Adam and dodge chrysler jeep! You guys are the best!
Short turn radius
I purchased pre-owned 2020 1500 SLT in February of this year. The truck rides comfortable and has plenty of room front and rear. My and I both enjoy it. My only drawback is the turn radius (lock to lock). It lacks compared to my wife's 2018 Yukon SLT, or the 2016 Ram I traded in. Have to many times maneuver twice to park it going forward or reverse. Otherwise happy with our purchase.

Great Experience!
The staff was courteous, I felt like they listened to my needs, and I felt like I was a person, not just a shopper that they were helping. I would recommend this dealership to a friend any day.
Great Truck
I did my research and test drove several models. The GMC 1500 Duramax does everything I want it to do and more. Great gas milage, nice power and very comfortable.

My Hat's Off To Those Involved
On February 21st.,2023, we took our 2022 Santa Fe to Earnhardt Hyundai of Scottsdale for routine maintenance & factory recall. After driving home, approx. 45 miles, the car set in our garage undriven until Feb. 23rd. On that date I found a considerable amount of oil under the car. In further investigation and checking under the hood, I found the engine compartment saturated with motor oil. I immediately called Earnhardt Hyundai of Scottsdale who contacted Valley Towing to pick up my car and deliver it to their Service Dept. The service mgr. contacted me by phone within two hours to tell me they located the problem which turned out to be the dip stick had failed to be fully replaced. He also assured me that they would clean up the engine compartment and return my car the following day. On Feb. 24th., Howard (Store Greeter), called to tell me they had completed replacing the engine oil, washed the car, detailed the engine compartment and would deliver the car to our home with one hour. As promised, Howard arrived at our home with the car and it was as clean as the day we made the new car purchase. Howard also filled the the gas tank and offered to clean up our garage floor. We're all human and capable of making mistakes as did the mechanic, but the follow up by each Earnhardt Hyundai Store Employee involved in this matter was professional, courteous and understanding (including the store phone operator). Even though we have a Hyundai Dealer closer to our home, we're certain to use only the Scottsdale Earnhardt Hyundai Dealer for our future service needs and vehicle replacement when due.
Best truck I’ve bought
The features and styling are very aesthetic. The truck has very smooth handling and response. I am impressed with the response from the Diesel engine.

Look for Jaime
Noticed some of the reviews on here for Rollit motors are not good. My husband and I have purchased two vehicles from this dealership and we only have good things to say. We worked with Jaime the two times he was great honest, available and offered great customer service. The two vehicles purchased are still in perfect conditions. I highly recommend.

Nice Services.
Nice Services. I love there Services.As an avid car enthusiast, purchasing the was a decision I made after months of research and anticipation. Now, after driving it for several weeks, I can confidently say it has exceeded all my expectations. First impressions matter, and the sleek exterior design of the certainly grabs attention. Its aerodynamic curves and stylish accents give it a timeless appeal that turns heads wherever I go. The attention to detail in the craftsmanship is evident, from the precision of the body panels to the quality of the paint finish.

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…..
