Alex Fierro was very helpful and was able to get our vehicle in for service right away and he helped us get best deal. Thanks Alex!
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 just got new Equinox EV with good discounts and payment rate applied for... But car cleanup n readiness should be a bit better for delivery.
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.

It was a long 5 months (due to back ordered parts) but DeAnthony made it such a breeze. He gave me weekly updates, answered all my questions thoroughly, when I needed a rental, he got it for me with no problem and had some of the best customer service I?ve ever experienced. I will always be returning for any services my jeep may have. Your mechanics are so detailed, they made sure all issues were fixed before they released my truck. I really appreciate all of you, you guys have an awesome team! Thanks for taking care of me!
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.

I had a really good experience today with Nilson and Flo! This was my first time ever getting a service done with Toyota and the staff and service went above my expectations. The whole process and the staff were very transparent about the cost and maintenance of my vehicle. Additionally every employee that I spoke with from the individual that checked me in for my service to the very end at check out was extremely kind!

I had a rough first experience at Mac Haik Chevrolet’s
I had a rough first experience at Mac Haik Chevrolet’s service department, but Brian Caldwell, the Service Director, completely turned things around. He personally followed up the same day I voiced my concerns, sent a mobile tech to my house to handle the software update, and later arranged for a porter to deliver a loaner and pick up my truck for a roof recall and additional service. They performed every repair as promised—on time—including the roof fix, oil change, tire rotation, and a minor interior issue. Brian kept great communication throughout, even with our busy schedules, and treated my time and situation with real respect. What started as a frustrating experience turned into one of the best service recoveries I’ve ever seen. Huge thanks to Brian, his team, and Mr. Mac Haik. This is how a dealership should be run.
