Great Experience
Austin Rizzotti was very professional and made the purchase of our new auto a real pleasure. He never pressured us to make a sale. The experience was different from any other car buying we have had.
I have the 1500 double cab with standard bed.
I have the 1500 double cab with standard bed. The reason I have this vehicle is I really like the 6.5 foot bed. The crew cab with same bed is just too long. The things I dislike about this model is that it only comes in the SLE model. For the 2025 that means the external mirrors do NOT have a power fold in and it does not have a seat memory for more that one driver. The power fold in for the mirrors is extremely important to me.

Loved that the showroom has natural light—not cold fluorescent stuff. You can see every detail on the paint. Staff uniforms look sharp too—more like a boutique than a bank.

We came for a Terrain, left with an Acadia. Looks way more impressive in person than online. The tri-zone climate control is a lifesaver with kids.

If You Want the Best; This is the Dealership!
I have been with this dealership for 30 years and I have recommended this dealership to family and friends because CUSTOMER SATISFACTION is important to them. From the sales people to the service department, they are professional, courteous and everyone tries hard to make sure your experience buying a new or used car is a great one. I bought my grandson's 1st car at this dealership and he now understands why I but my cars with this dealership.

A surprisingly pleasant experience
Best experience I've ever had with a dealership service department! Michelle and Jack picked up my car and returned it to me!! Friendly, clean, pleasant and competent. So rare these days. I would recommend them highly, especially over Freehold Buick. Freehold Buick tried to rip me off on several occasions. They lied to me and were disrespectful. I'll never go back to Freehold Buick, but look forward to working with Jim Curley Buick of Keyport in the future. Thanks so much.
