Welcome to Dieffenbach GM Superstore

Best service ever! Andy made the process so smooth for us. Everything about this dealership is wonderful!

My husband and I recently purchased a new Tahoe, and Stephen, Rusty, and staff were so kind, helpful, and easy to work with! If you are ever in the Rockingham area and looking for a new ride, check these guys out! Thank you again to Dieffenbach for all of your help and hospitality last week! We appreciate you all!

we where traveling from Southport to Niagara Falls, stopped on our way in Rockingham. My husband hear this noise and said it’s probably our brakes. We pulled into Dieffenbach dealer ship, and ask f they could help. They repaired the brake pads and roter system. Big shout out to the Service Manager that day, and the mechanics which did a super job getting us back on the road. Thank you for your excellent service. Now we where abel to meet our kids at Niagara Falls and we celebrated our 50 th anniversary. We will always recommend Dieffenbach Dealer to others. Super job done well.

Very good experience. I had dealt with sales person before.

We have always dealt with Dieffenbach for all of our car needs. We are very loyal to them as they are to us.

The teamwork is excellent and customer service is on point.

Tara and Tori and the hole staff are really great. This is the best experience I've had at a dealership. I would highly recommend them to anyone looking for a new or used vehicle.

My in-laws bought a Buick Enclave and were very pleased from start to finish. I bought a GMC AT4 and I also was very pleased. Robbie Singletary was our go to guy and he did a great job. He took the time to show my in-laws how to use the new technology that the Enclave offered. Trust me, they needed all the help they could get. Hahahahaha. I would recommend if you’re in the market to give this team a shot before pulling trigger somewhere else. 5 stars for me!

Deffenbach Cheverlot an outstanding dealership with excellent service. Diffenbach Cheverlot has set a standard for excellence that other dealerships will have to work extremely hard to try and match. My 2010 Camaro had a prior problem with eratic acceleration and deceleration which left me stranded. I had my car towed to another dealership to try and correct the problem. They replaced a pedal assembly, but 75 miles later the same problem left me stranded. This time I had it towed to Diffenbach Chevrolet. I was pleasantly surprised, how quick I received a phone call from their technician who had quickly diagnosed the problem. He explained in detail the reason I was experiencing this problem was due to a failure with my Camaro's computer board that was bad and needed to be replaced. The technician had one in stock and could replace the same day. The tech also reassured me that this would fix the problem. I have had absolutely no problems with the car since the repair. I have driven it 2,700 miles since being repaired. I am so pleased with this dealership that I trusted them to install a performance upgrade with cold air intake and a new Borla exhaust system. Not only is my car repaired, but my new performance upgrade can be felt and heard. I'm so pleased with my experience with this dealership that my next vehicle purchase will be with Diffenbach Cheverlot. Everyone from the owner, to sales and service set a Gold Standard of Excellence. I encourage you to try Diffenbach Cheverlot in Rockingham NC.
