Rarely ever post about dealerships (unless it bad). This place really made my trade-in and purchase, effortless. They gave me a great value on my trade-in and stuck by their word. Also is refreshing to see a dealership not rip you off with ridiculous add-ons and fees. Overall and really pleasurable experience. I came an hour and a half from Queens and they definitely respected my time. I'd say its worth the trip if anyone is in the market for a GMC.

Service appointment was on time and service conducted was done in a timely manner. The only issue which seems to be a regular occurrence at Riverhead GMC is that they do not use paper mats to cover your carpeted mats that’s always have grease and dirt that I must remove after services provided

Paul, our Salesperson, was wonderful. On Saturday, he spent 5 hours with us test-driving 4 GMC trucks and then doing paperwork because we ended up buying the GMC DENALI 6.2 liter. The team had it ready for pickup on Monday. The whole team, Paul, Billy, and Ted, were wonderful.

I always have a great experience at the Riverhead GMC. All of the employees are friendly and they all have great work relationships with each other. Jeff Nammack is always most helpful and greets people with a friendly hello and keeps you updated as the car is being serviced.
This dealership kept me informed of what was going on with my car. They treated me very well. Billy, Malaika, and Peter Visconti were more than helpful to me.

I can’t express how happy I am with the service provided. I brought my car to Riverhead after sever appointments at another dealer failed to fix my vehicle. The staff at Riverhead was very accommodating and professional. The vehicle was fixed in a timely manner and I was kept updated on its progress. Even with it being further away then 3 other dealers I will be a returning customer and will highly recommend the establishment.

Extremely over priced. I received a quote for a Sierra SLT priced at 65k, with 4k down and $784 a month for a lease. Acura offered me an MDX worth 64k for around $1,300 down and $625 a month for a lease. What a shame
