Auto Repair in Firestone, CO
About 20 miles northeast of Boulder, a 30-minute run via I-25 and Highway 119. The auto repair shop Firestone drivers trust for honest service, real diagnostics, and a three-year warranty that travels with the vehicle.
Firestone is growing, working, and full of capable trucks. We see Firestone diesel pickups, ranch trucks, fleet vehicles, and family rigs every week. The drive is 30 minutes down to Boulder, but Firestone customers tell us it is worth it because we actually understand what they bring us. Diesel-experienced mechanic on staff full time, 4x4 outfitter on site, fleet pricing for multi-vehicle operators, and a 3-year NAPA warranty honored at 17,000 locations nationwide.
Worth the short drive.

What Firestone drives.
Firestone has changed fast. What was a small town a decade ago is now a growing community of around 17,000, with new neighborhoods spreading and oil and gas industry presence holding strong. Firestone is a working town with a foot in two worlds, the Front Range outdoors lifestyle and the Weld County energy economy. Some residents commute south to Boulder or Denver tech jobs, but a significant portion work in oil and gas, trades, ranching, and construction. The vehicles reflect the work, capable trucks that earn their keep, and we are built to take care of them.
