My visit met expectations.
My visit met expectations. They provided additional service options they feel are necessary, however dealer suggestions for service at mileage intervals do not always align with GM recommendations, so I try to review GM recommendations first. Good example is oil change. Dealer recommends at 5k, but service manual says 7,500 or based on oil life monitoring system.

It was by far the best experience of purchasing an automobile I’ve ever had. Very courteous and helpful. I actually went to GMC dealers in Va. and NC and they couldn’t help me get the SUV I wanted. Went to Cars.com and submitted 3 notice of interest to 3 different dealers and Zeigler responded within 5 minutes. No haggling and gave me a more than fair quote. Everything went smooth and finally heard from other dealers an hour or two later. Really appreciate the professionalism. Love my truck and it was delivered today! Thank you for all your help.

Went to just look at new cars, Wrong idea!
Went to just look at new cars, Wrong idea! We met Dexter and he was the best car salesman I’ve ever dealt with. He wasn’t pushy, He let us look, and then he gave us a few cars to look at at what he thought we would like. Found a car in a matter of an hour. Went back the next day and boom it was ours. They had the fastest and the best system at purchasing a car, simple and easy no more back-and-fort smooth and easy and I would recommend Them hands down.

Working with Drew at Briggs Nissan of Manhattan made the car-buying process remarkably smooth and stress-free. From our initial interaction, it was clear that this dealership operates differently—prioritizing genuine relationships over high-pressure sales tactics. Drew took the time to understand our needs and guide us toward the right vehicle, without ever making us feel rushed or pressured. In the end, we felt confident that we reached a fair and mutually beneficial agreement. Gabe in the finance department further reinforced the dealership’s commitment to a seamless experience, handling everything efficiently and transparently. If you’re looking for a dealership that values trust, respect, and long-term relationships, I highly recommend connecting with Drew at Briggs Nissan.

We've had a great experience with Key Auto Mall GMC
We've had a great experience with Key Auto Mall GMC purchasing our new 2025 Acadia. Brian MacGee was wonderful to work with along with General Manager Theron Maring and all the other great staff. Brian especially has spent a lot of time going over all we need to know about how this car works and has several times answered more questions since we purchased the car a week ago. He helped us purchase new cargo mats and get the protective coatings on the car, inside and out. Brian has been professional, friendly, and so helpful to us. We highly recommend Brian and the Key Auto Mall GMC team and will definitely consider them for our next auto purchase.

I had an outstanding experience getting my 2022 Chevy Traverse serviced here. After bringing it in for a transmission issue, the team diagnosed it quickly and even provided a ride home so I could finish my workday. My service advisor, Brian, was exceptional?he stayed in constant contact with updates. I was relieved to find out the replacement was covered under the powertrain warranty. They sourced a new transmission locally and finished the job right on schedule. They even picked me up to collect my vehicle! I?m driving away with total peace of mind. Highly recommend Brian and this service department.
