Used 2020 Chevrolet Silverado 1500 trucks for sale near South Windsor, CT

I bring my fleet vehicle here for repairs/maintenance. Other dealerships have treated me like a second class customer because the fleet company pays for everything. I have never once felt that way at Sullivan's. They are always kind and have gone above and beyond for me at times. My husband became a loyal customer here because of their great customer service.

I have a 2020 1500 RST with the 5.3 engine and 8 speed transmission. My truck now has 67,000 miles. The acceleration is outstanding and smooth from gears 3-8. Probably could use more torque for gears 1-2, but not weak by any means. I have had no mechanical problems outside of the clunking rear suspension which was fixed by retorqueing the rear leaf spring suspension bolts. Other than that minor issue, it has been very reliable. I have heard these transmissions have had issues, but nothing that has caused issues for me. It has the 60-70 MPH shutter that is common to these transmissions, but I have learned how to drive to avoid the shutter, as I did with my 2011 1500. Overall pretty satisfied at this point. Comfort and amenities could be better for the front seats for the price, but I bought it knowing that. FYI my front brakes at this point are still 50%, and I have invested very little outside of a few fluid exchanges and routine maintenance. Excellent fuel mileage: 20 mpg with 50% highway vs city driving.

Bought remotely from a couple states away. Opted to arrange my own financing. Ken & Joe were very patient, holding the vehicle (with minimal deposit) while lender rqmts. for availability of funds were met. They made it EZ. An all around awesome experience! When I went to get the vehicle I purchased, the only distraction was their impressive inventory!

Purchased new a 2020 Chevrolet custom Trail Boss in Satin Steel metallic, it has been great. I just turned 80,000 miles with no issues, it’s been a pleasure to drive, just replaced brakes and tires for the first time at 75,000 miles . I have also purchased new a 86 F-250 and a 01 GMC 1500 which also were great trucks and sold with 190,000 miles on them. Maintenance is key Chevrolet did a great job on the exterior of this truck, love the look and color. Nothing bad to say only a positive experience.

very good . the pm's that werte compleated were checked off and not everey box was checked off like last time . it i see a box checked off and that service was not required or compleated i will go somplace other than your location. a good pm programhave has certain guidelines to fallow. the person compleating the pm's should not check of a pm that he did not comcomplete, and checked off after completion. i hav worked with vehicle pm programe in the U,S MARINES AND U.S Army and U.S Air Force . alos for the city of chicopee for 30 years. it was unacceptable and quite shocking when i picked up my truck to find all pm check boxed checked . this was not my last pm with you but the one befor. ,

Best truck I've ever owned. Great power...good fule economy on highways. comfortable and roomy great bose sound system No over dramatic fanciness but practicality. I like the design and added features such as a sliding rear window power outlets inside and in the bed. 20k miles on her so...maybe too soon to tell?

Service is always tops Sales department the best Would recommend to anyone looking for a new, used car or service. Blasius Chevrolet is, by far, the best dealership in Connecticut

Awesome Truck except for transmission troubles. Very good gas mileage and comfort and ride are the best. A very dependable truck with lots of great features. Back up camera is great.

On Saturday, June 7, my daughter and I had an outstanding experience at XXX Chevrolet. While my initial intent was simply to support her in purchasing her first vehicle, I ended up trading in my own car and driving away in a brand-new 2026 Equinox — while she purchased a 2025 Colorado. Both vehicles impressed us during the test drive. The safety features, interior design, storage space, and overall aesthetics sealed the deal for both of us. While comfort and safety were top priorities, what truly set this experience apart was the exceptional service we received. Steven connected us with Brian, an outstanding sales specialist who was both highly knowledgeable and incredibly personable. He built immediate rapport, listened carefully to our needs, and guided us to the right vehicles without any pressure. The process was smooth and efficient — we were both driving off the lot the same day! The dealership itself was clean, welcoming, and even treated us to a delicious lunch during our visit — a thoughtful touch that made the day feel even more special. I’ve purchased several vehicles over the years, but nothing compares to the level of service we received from Steven and Brian. I highly recommend them to anyone looking for a car-buying experience that’s professional, honest, and genuinely enjoyable. Judi and Jackie T.

Have had this since new in 2020. No major issues. Transmission is rough when cold, but not an issue. Three years in and no major work. One brake adjustment and oil changes. Other than that it’s been a great truck.

Worked with Steve, didn't end up buying but he was super nice and upfront with us. A much better experience than some of the dealers we talked to on this journey.

Great dealer. No hassle. In my new vehicle the same day. Smooth transaction. Very happy with whole experience.

Koster at Full Throttle was very thorough and worked around my schedule for the new truck

I've bought 2 cars here and am headed in soon to buy another. THE BEST.

Had a great experience buying a used car here. Everyone I dealt with was friendly and knowledgeable. I never felt pressured, and being a single female, that was important to me. They gave me a fair price on my trade-in, and their cars are reasonably priced. Will Anderson was a terrific sales guy, and Jill and Matt guided me through all the paperwork. *Highly* recommend this dealership!

Edwin was great to work with from the beginning. He reached out shortly after I inquired about the car and scheduled a time the next day to take a test drive. They were able to complete the purchase that day so I could take the car home. Overall, both Edwin and their Finance department were easy to work with.

Had a great buying experience here at terryville chevy. My salesman Peter was great and very knowledgeable. I highly recommend going here!
