Always great service at Arlington Heights GMC.
Always great service at Arlington Heights GMC. Mark Lubrano is wonderful to work with. He always gives you special attention to make sure all your service needs are met.
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!

I have brought my vehicle in for every oil change I have needed. Always courteous and professional, my car gets a diagnostic check every time and is freshly washed. I like that the Service Department send out coupons, and making an appointment is easy online or with a phone call.
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.

Located the vehicle on-line, inquired and was sent a video of the vehicle. With the information provided I traveled 5 hours each way to test drive and purchase the vehicle on a Saturday. The staff was courteous and the purchase went well.
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.

Very easily booked my appointment online, was greeted and written up. My service advisor was informative, professional, courteous and respectful. The service I had done was completed in an appropriate amount of time and my truck was returned to me washed and dried. The waiting area was clean and comfortable. Two thumbs up!
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!
