Very responsive and easy to work with even though I’m out
Very responsive and easy to work with even though I’m out of state. I’ve had a great experience with them!
A Beast when it comes to hauling!
I love how the truck pulls and rides when towing. It will give any driver the confidence to tow anywhere. I haven't had a single issue with it. I love the way it looks and couldn't be happier.

I purchased a 2025 Mazda cx70 with the help of Kenneth at Boucher. He wasn’t pushy and actually made the whole car buying process a little less terrible! The manager was also willing to work with me on numbers to suit my budget. If you’re in need of a Mazda, ask for Kenneth!

I am a new customer to the Johnson auto group, and after
I am a new customer to the Johnson auto group, and after my experience will certainly be a returning customer. The sales staff, specifically Shelby, was amazing. They were attentive, fair, reasonable, and transparent throughout the entire process. I am so happy I decided to purchase from Johnson GMC. Ultimately, I left the dealership with a new truck and a great experience where I felt that I was a valued customer and that my business was truly appreciated.
In about 15 vehicle I had, this the best one
This truck just need nothing, comfort, strong, and beautiful, it's great for work, and for personal use, my next car will be the same but new

As a business customer, dealership does not accept Purchase Order. We must abide by the PO terms in the future which is a legal binding contract. Unfortunately, if Hirning will not accept a Purchase Order we will no longer be able to provide check on delivery.

We had a great experience with this dealership!
We had a great experience with this dealership! I highly recommend using Jeremy Tabangay as your salesman. He was very polite, and wasn't aggressive in his sales tactics. He really made you feel like you weren't just a number to him. He also did a follow up after we purchased, just to make sure that everything was going well. I would also like to give Matt (finance department) a good review. He was fun to work with on the financing of our vehicle, and didn't pressure us into buying any add ons. He was also very quick in getting all the paper work filled out. We really enjoyed our entire visit there. I would use this dealership again in the future. Especially, if I was working with both of them.

I bought an Alfa Romeo SUV recently from R21 Motorsports.
I bought an Alfa Romeo SUV recently from R21 Motorsports. After 4 days I began experiencing engine trouble. I also purchased an extended warranty with the car, a practice I would recommend for ANY car purchase NOWADAYS. The warranty broker Nick S. worked tirelessly with the dealer to work out a solution that worked for all parties involved. This was an unfortunate situation, but to Tad and the dealership's credit they stood behind the product they sold and worked out a solution that was fair for all parties involved. Based on my experience with a difficult situation that they stepped up on, I would recommend purchasing a vehicle from R21.

My husband and I live in the Cincinnati area and found a new 2025 Yukon Elevation at Ron Marhofer for a great price. The price was as advertised online- no bait and switch with employee pricing or discounts that only certain groups qualify for- just a flat dealer discount. We worked with Steven and the process was smooth and easy- definitely worth driving 3.5 hours.

Dealing with GMC of Attleboro is a stress free
Dealing with GMC of Attleboro is a stress free experience. The product was explained to me along with all the financial options available to me. I was treated with respect and professionalism. The employees especially Dave, Paul, and Dennis made my purchase easy and enjoyable to the point where I was totally gratified and excited to make the purchase. I intend to do business with them in the future and would highly recommend them to anyone who is looking for a new vehicle to purchase or lease.
