Three Cars Later
I’ve purchased three cars from this dealership, the team is great and transparent. No high pressure sales. In looking for an SUV they were the only lot that had a physical vehicle on site. Don’t waste your time going somewhere else.
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!

Cassidy helped me get my dream car!
Cassidy helped me get my dream car! Top of the line service. Phenomenal professionalism and very friendly. Oh and this was my SECOND car from here; these guys are the PLACE you want to build a good relationship with so you can always feel safe and secure when getting a new set of wheels.
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.

CARMAX!!! What can I say, but a great place to buy
I have never bought a car so easy as I did here. The process was quick and painless just the way I like it. The finance part for the car took like a 10 minute process. The no haggle price is the price and there's no back office person dictating the sales rep to get more money more money on the sale. It's all done at the desk you sit at drone start to finish, just you and the sales rep. I rolled out in my new car in a half hour total.. Loved it(and car is awesome too)
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.

Best used car buying experience!
This was the best and most cordial car buying experience ever. Alin and Mid are honest and a pleasure to deal with. Their inventory is full of quality vehicles and reasonably priced. If you want a great ride and a great deal you have to check out A&M.
Best truck we have owned!
Truck meets my and my wife's needs. She loves her and I do to! Love sport mode and the tow hail mode. Rides like a Cadillac!

I brought my SUV in for a repair on 11/19/24. Josh Baldwin, the service manager, was very proactive communicating with me via text on the diagnosis, estimated cost to repair, and estimated time to repair. Their technician made a video showing and explaining where the problem was and what was needed to fix it. Their entire service process felt open and honest, unlike other dealers' service departments I've dealt with.

Nice dealership
Really very nice people that work at Newberg Chevrolet. The reason I ended up buying from them was because of Kari Mayton. She knew I was interested in a particular vehicle but at that time I wasnt ready to purchase it. She didnt forget about me and called me a couple months later to see how I was doing and to see if I was still looking for a car. She is an amazing part of the dealership and so glad to have had her help in finding the car I wanted. Thank you so much Kari. You rock! And thank you to Billy Brady for your knowledge and not being scared to go for a test drive with me and my lead foot !

I have been to so many car dealerships through out my driving years. I love westlies because they do not follow you at lot asking tons of questions. Of course I'm there to look att cars and when I find one I'll come to u. Which I did. I found 4 that I loved. They let me test drive each one. I ended up choosing the Chevy equinox. It was beautiful not a thing a long and very spotless. The lpaperwork took no time. A lot of places takes a good 8 hours not westlies. They were very nice. I told them the price I did not want to go over and I got it for less..I will tell everyone to go there to buy a car and they will not be disappointed..I got 4 free oil changes for free and check my engin̈e and tires. They also come and pick up then drop it back off when it's all Don r. I am very happy customer. Nancy Peebles
