Coal City is a community with deep mining roots and a lot of people who still work with their hands, so it's no surprise that trucks are king here. Our new inventory features the GMC Sierra 1500 for everyday work and weekend projects and the Sierra HD when the load gets heavier. Families growing along the Coal City corridor often lean toward the Terrain or the three-row Acadia.

Because we're so close, you can easily stop in for a side-by-side test drive after work instead of planning a big trip. If you're curious about electrification, the Sierra EV and Hummer EV are covered on our electric vehicles page, and our team can explain range, charging, and available incentives.

Not every Coal City driver needs a new truck. Our pre-owned inventory includes used GMC trucks and SUVs alongside other makes, each inspected before it's listed, giving you dependable options at a range of price points and mileage.

You can also explore our CarBravo inventory for additional pre-owned selection. If you have a vehicle to trade, use our trade-in page to get a sense of its value before you stop by.

Our service center is staffed by certified GM technicians who handle oil changes, brake service, battery and electrical work, and tires, plus transmission service, HVAC/AC repair, and check-engine diagnostics.

Work trucks that haul gear and trailers around Grundy County take a beating, and routine maintenance is the best way to keep them on the job. Coal City drivers can book online at our service scheduler or call our service department at (815) 242-7501.

Our finance team works to match Coal City buyers with terms that fit their budget, whether you're financing a new Sierra or a reliable used SUV. Start with our online pre-approval tool, or run your own numbers with the payment calculator.

If you like a new truck every few years, ask about leasing on our finance center page. Our team explains every line item in plain language, with no pressure and no surprises at signing.
