I had a great experience purchasing my new 2025 Honda
I had a great experience purchasing my new 2025 Honda Civic from Nucar, after a few mishaps and misunderstandings with the online team Dave Belanger and the Manager stepped in to make everything right. From that point on it was a great experience and I highly recommend working with Dave for a 5 star experience!

2021 GLC300 4matic
I absolutely love this compact SUV! Coming from a Subaru Outback, this is light years above and beyond for same year. A quiet cabin is my top want for buying a car. This cabin is quiet and relaxing inside. I’m tall and there is plenty of room. The seats are incredible! Can’t wait to take it on the roads in winter.

Auburn Nissan
I recently went in for an oil change and found that my rear differential was toast. I had to have a new rear end installed which affected the ABS module which also had to be replaced. Through out the process, Dennis in the service dept. kept me well informed of the progress. They kept to the original estimate and also gave me a new loaner vehicle to drive. I am very pleased with the outcome and thank you Dennis.
GLC43AMG
I have the GLC43 AMG and it's awsome! It has plenty of guts and is extremely comfortable. I would highly recommend this vehicle to anyone.

feels like family
I purchased my car here and only bring it here for service. Its become a second family. You can really tell they care about their employees as everyone you encounter is very pleasant. I will always recommend this dealer to anyone who asks
Exceptional Comfort
I have had this vehicle for only one month so have not developed much experience with it. I did take it on a 1400 mile trip two days after purchase. It ran well, was very comfortable to drive, made for a very easy trip, was great on gas mileage, and it is very quiet inside the cabin. Seat comfort is exceptional and this, being our first experience with heated seats and steering wheel, was most enjoyable.

Very Accomidating
I am a super busy person. I called to schedule an oil change and they met every need that I had. Including letting me go before they open to have my oil changed. It was done so fast and effectively I was not late for work and I could not be happier. If you want a place that will service your car with a smile...and get it done right. This is where to go.

Great experience
Have had great experiences here.bought a 2009 Jeep Grand Cherokee 3 years ago that I’ve had no problems with. we just passed it down to my Daughter.A couple months ago we went and bought a 2014 Jeep Grand Cherokee. When we test drove it we mentioned that the rotors looked a little beat up when we went and picked up the jeep it had brand new Pads and rotors on all 4 tires. We only mentioned the front. They go above and beyond to make sure there customers are happy. Defiantly will be going back for a third vehicle next year when my other daughter gets her license

Absolutely fantastic experience
I bought a 2011 Chevy Suburban. Liam and John were fantastic. Amazing is an understatement. I did not know there are actually car dealerships anymore that go this above and beyond and as pleasurable to deal with. A+++++++++

I have worked with Brian for quite a while and I have been exceptionally pleased with the service that he has given me. I feel very comfortable having Brian in charge with the service department because he stays on top of what has to be done. I have found that Brian is very caring, professional, and knowledgeable and when I leave the dealership I know that everything was done perfectly. Janet Edsall Fields

Highly recommend this dealer, and Asia Allen, specifically. She helped me sort out a deal on a vehicle remotely, and it’s one of the easiest, if not easiest, car buying experiences I can recall. She’s very prompt, very friendly, made it easy to come to a fair price, and even arranged transport for me. Total white glove service, highly recommended!
