More than a repair shop

Built by enthusiasts. Backed by community.

Founded in Haymarket in 2018, Bull Run 4x4 moved to Manassas in 2025. Our belief remains the same: customers deserve honest answers, carefully selected parts and work that performs long after it leaves the bay.

We help drivers understand their vehicle—not just hand them an invoice. That same straight-talk approach powers the NOVA Jeep and Virginia Offroad Trails communities we help lead.
