Best experience this retired couple has ever had buying a
Best experience this retired couple has ever had buying a vehicle. Masha was a knowledgeable, helpful, and no pressure sales person. Of the 3 dealerships we contacted this one excels in inventory, best deals, and organization. Rochester was a huge disappointment when the fast talking pressure type manager got involved, we walked away. Nu Car in Tilton wouldn't honor their posted price on Auto Trader and no mention of the dealer incentive, just their version of MSRP.

I want to thank everybody at S&J Motors.Especially Stan and Nick. They went over and above to make sure got the SUV we wanted.Very professional,caring and I highly recommend S&J to anyone needing a car/suv etc. They truly care about their customers. Some other dealerships should learn that lesson. Extremely kind, not pushy, and S&J has been in business a long time. We are extremely grateful and happy.

Excellent service with very reasonable price.
Excellent service with very reasonable price. Took care of my car like his own vehicle. I would definitely recommend this dealership for service. The mechanic provides details of what he has done.
This is an attractive and enjoyable vehicle.
I traded my Chevrolet Silverado for this GM Certified GMC Sierra 1500. It is an attractive and enjoyable vehicle. Some years ago I had a GMC and really prefer them over a Chevrolet. This vehicle is just what I need for hauling and general driving.

Matt at Tim's truck capital was awesome to work with.
Matt at Tim's truck capital was awesome to work with. He answered all my questions and was willing to work with me being an out of state purchase. I found a truck in state instead, but I'd definitely work with Matt again if I need another work truck. Great business with a great selection of trucks
