AutoNation Nissan Chandler review

Very smooth process from start to finish.

Very smooth process from start to finish. Arrived at appointed time and was immediately taken care of. Marco, my technician, took the time to keep me updated on the car's progress. When the work was finished, I received my paperwork and went merrily on my way until the next service.

Peoria Ford review

I wanted to commend the service department on their

I wanted to commend the service department on their professionalism. I had Johnny take care in a recall for my Ford Transit Connect. They did an overall inspection and suggested a few services that should be done. He didn’t try to scare me to do them and did only the services I authorised after he took the time to explain how they perform the work. Upon picking up my vehicle Spencer who has helped me in the past was great in helping delivering my vehicle. I also want to thank Alex in Mobil Vehicle Service for setting up my oil change. Great Team!!

2021 GMC Sierra 2500 SLT review

Early to tell truck has less than 100 miles

Truck was bought specifically to our travel trailer. We have to wait for 1000 break in before we can tow the trailer. So far the truck is very quiet, smooth running, & comfortable to drive. We were pleasantly surprised at how much interior storage space is available. Having the bed steps before rear tires and in the bumper sides is very nice. Bed rails are even with my shoulders so the steps get used a lot.

Blasius Pre-Owned Auto review

I bought a 2018 Nissan pro x a little over a year ago.

I bought a 2018 Nissan pro x a little over a year ago. I drove from ny to look at it it was clean except for front bumper was hit in corner and paint was scraped. They repaired the damage perfectly by the time I picked it up. I was impressed by their professionalism. The only thing that I thought was a little extravagant was the dealer fee. We negotiated a fair price and now it’s mine. I’ve had the vehicle for over a year and it is flawless. I felt I needed time to make a fair judgement of the vehicle before my review. I would not hesitate to buy another vehicle from thi dealership

AutoNation USA Albuquerque review

They will work with you until you are satisfied.

They will work with you until you are satisfied. I personally went back like 4 times to find the right car, Derek was nice enough to open my options to out of town cars and ship them to my local dealer. Jeremy,Derrick,Abrian,Bobby and Daishon all worked so hard to get me the right numbers and into the right car that worked for my budget and my bug family. Will for sures be taking a family member or two to them!

Corwin Buick GMC Cadillac Reno review

I am so impressed and appreciative of the service team

I am so impressed and appreciative of the service team here. Yes, it can take a long time to get an appointment - depending on what you need done, but the last two times I've brought my truck in for service, they fixed things the other auto shop repaired incorrectly, helped get me to and from the car rental place, and had exceptional communication before, during and after. Their staff is friendly and professional and I trust the work that's done, is done correctly.

im not new to buying cars.

im not new to buying cars. ive owned hundreds and currently own 6 cars , 6 trucks and 3 motercycles. i however am new to the excellent service I received. Ill never buy a car from anywhere else. Bergeys team were the most knowledgeable and and easy to deal with ever. Then theres the deal part. no other place could even come close to what they came up with for me. if I had to describe everything in brief , " like a well oiled machine" When It came time to show me how everything works 3 of the Bergeys team came out. and all my questions was answered. I made the best choice ever Going to Bergeys GMC. The kind of place where you can stop anytime with questions and its not a bother

Worked with JT and Max for the purchase of a 2020 GMC Acadia. We went in with a set monthly payment idea and they worked with us until we got to where we wanted to be. 10/10 customer service experience! Even if things wouldn’t have worked in our favor, we would have left knowing they did everything they could and actually care for their customers! Highly recommend!
