Welcome to Sims Auto Park

Sims Auto Park is under new management — and Warren, Ohio is going to feel the difference. New leadership means a renewed commitment to the community, a higher standard of service, and a buying experience that puts you first from the first click to the final handshake. Everything we do is now guided by The Sims Standard — our pledge to deliver transparent, pressure-free, relationship-driven service at every touchpoint. Whether you're shopping for a new vehicle, browsing our pre-owned inventory, customizing a truck, scheduling service, or ready to sell — you'll notice something is different here. That's intentional.

Sims Truck Center — Warren, Ohio's Custom Truck Destination

Sims Truck Center is more than a place to buy new and used trucks in Warren, Ohio — it's where truck owners come to build the truck they've always wanted. As an authorized dealer for RealTruck and Rough Country, two of the most trusted names in truck accessories, our factory-trained truck specialists can customize virtually any build. Lift kits, suspension upgrades, wheels and tires, off-road lighting, tonneau covers — if you can imagine it, we can build it. Whether you're starting with a brand-new truck or bringing in your existing one for an upgrade, our team is ready. That's The Sims Standard — expert guidance, no pressure, and a result you'll be proud to drive.
