A century of
honest work.
Since 1920, Sternquist Garage and Tire has been a cornerstone of automotive excellence in Boone County. Four generations of mechanics have worked under this roof, and the same standard has held the whole time: do the job right, charge a fair price, and treat people like neighbors.
We pride ourselves on a tradition of quality workmanship and a commitment to keeping you safely on the road — whether that means a $35 oil change or a complete engine rebuild.
From 1920 to right now.
Sternquist Garage opens its doors in Boone, Iowa.
Expands into tire sales and full-service truck repair.
Adds modern diagnostic equipment for fuel-injected vehicles.
Invests in OEM-level computer reflash and module programming.
Still family-run. Still keeping Boone County on the road.
Honest pricing
No upselling, no surprises. We tell you what's wrong, what it costs, and what it doesn't need yet.
Real diagnosis
We trace problems to their actual root cause — instead of replacing parts and hoping for the best.
Built to last
We use quality parts and back our work. The repair should outlive the problem.
