        Great 4 cylinder truck

        by Steve on 9/23/2026 2:01:15 AM

        I have only pulled a trailer one time and still got 18 mpg down doing 80 down the interstate. Otherwise this vehicle is used for commuting or recreating. I typically get 22-24 mpg driving MT highways to the mountains. The turbo has some spunk for getting up to speed and the five years I've had my truck no complaints.…

        Used Chevy Vehicles for Sale in Lawrenceville, NJ

        Chevrolet has been making reliable vehicles for over a century, and they still build tough, dependable cars, trucks, and SUVs today. Because they're so durable, you can count on a Chevy vehicle to perform well for many years. Ciocca Chevrolet of Princeton has a vast selection of used Chevy models for sale in Lawrenceville, NJ, and we look forward to helping you find just the right vehicle for your lifestyle.

        Why Purchase a Used Chevrolet Vehicle from Our Dealership?

        A used truck, SUV, or car will only cost a fraction of what you'd pay for a brand-new vehicle. That's because depreciation reduces a car's value by as much as 50% in the first three years. However, a Chevy is likely to run well for far beyond 100,000 miles. Trenton drivers can enjoy terrific value from purchasing a pre-owned Chevrolet vehicle that's already taken its biggest depreciation hit.

        Tags, taxes, and insurance also generally cost less on used cars. Since you'll be spending less on a pre-owned vehicle, you may be able to afford a nicer model with four-wheel drive or a sunroof. People in South Brunswick who like a model that's been discontinued, such as the Chevy Avalanche, may still be able to find one in our used inventory.

        Since Ciocca Chevrolet of Princeton is part of Ciocca Automotive in New Jersey and Pennsylvania, we're able to offer a larger, more diverse selection of pre-owned vehicles than most places.
