NAICS 811111 – General Automotive Repair covers the maintenance, diagnostics, repair, and overhaul of light-duty and medium-duty motor vehicles, including passenger cars, trucks, vans, and specialized government fleet vehicles. This sector encompasses mechanical and body repair services such as engine tuning, brake system restoration, suspension alignment, electrical system diagnostics, and collision repair using OEM and aftermarket parts. In the federal contracting landscape, this NAICS supports mission-critical mobility for agency fleets, ensuring operational readiness across civilian, law enforcement, and military applications. Services are often delivered under indefinite-delivery/indefinite-quantity (IDIQ) contracts, blanket purchase agreements (BPAs), or task orders requiring compliance with federal vehicle maintenance standards and environmental regulations. Top contractors in this space include TECH O. R., LLC, EXTREME GOVERNMENT SOLUTIONS LLC, MIDWEST TRANSIT EQUIPMENT INC, BHPE LLC, and IMPERIAL AUTO BODY & SALES, a mix of small businesses and mid-sized firms with specialized expertise in fleet maintenance, mobile repair units, and government-compliant bodywork. These contractors typically hold small business set-asides or 8(a) certifications, reflecting a competitive environment where agility, local service networks, and compliance with federal vehicle maintenance protocols are key differentiators. Primary buyers include the Department of Defense, Department of Veterans Affairs, General Services Administration, Department of Agriculture, and Department of Homeland Security. These agencies rely on consistent vehicle uptime for logistics, emergency response, veteran transportation, and rural patrol operations, driving demand for preventive maintenance, fleet modernization, and rapid-response repair services. The market is characterized by high opportunity density across regional fleet hubs, with recurring procurement cycles tied to vehicle lifecycle management. Contractors with certified technicians, access to diagnostic tools compliant with federal specifications, and experience in managing multi-site maintenance contracts are best positioned to compete. Demand is increasingly driven by the need for fuel-efficient and low-emission fleet repairs, aligning with broader sustainability initiatives across federal agencies.

Bidder counts reported on past federal awards in this NAICS (USAspending). An open opportunity has no bidders yet, so this is the historical norm for similar work, not a fact about this solicitation. Not all awards report bidder counts, and fewer bidders often means incumbent-held work rather than an easier win. Federal reporting of bidder counts fell from ~96% of awards (FY2016) to ~30% (FY2018 onward); the chart shows shares of reported awards, and washed-out stretches mark years with fewer than 30 of them.

J--Law Enforcement Vehicle Upfitting Services
Solicitation # 140FS126Q0128
The U.S. Fish and Wildlife Service, through its National Wildlife Refuge System Law Enforcement division, is soliciting a firm-fixed-price contract to receive, upfit, and deliver five government-furnished patrol vehicles—four Ford F-150 4x4 Crew Cabs and one Ford F-250 4x4 Crew Cab—configured to Class A (marked) law enforcement standards. The upfitting must include emergency lighting, siren and light controllers, communications and radio wiring, a prisoner cage, weapons rack, custom electrical harnesses, anti-theft systems, window tinting compliant with California state law, standardized graphics, and other mission-specific equipment. All work must be completed and each vehicle delivered within 90 calendar days of its arrival at the contractor’s facility, with final inspection and formal acceptance conducted on-site by the Contracting Officer’s Technical Representative prior to release. The contractor is required to self-perform the majority of labor, including wiring, installation of safety and communication systems, and other core upfitting tasks, and must disclose all proposed subcontractors along with the scope and percentage of work they will perform, ensuring subcontractor payments do not exceed 50% of the total contract value unless the subcontractor is similarly situated. The acquisition is structured under FAR Part 12 as a commercial item contract with a firm-fixed-price basis, and award will be made using a best value trade-off approach where non-price factors—experience, subcontractor disclosure, and past performance—are more important than price, though price becomes increasingly decisive as proposals become more equal in technical merit. The contractor must be registered and active in SAM.gov and must provide their Unique Entity ID in all submissions. Proposals must be submitted as a single PDF via email to the designated contracting officer, including the solicitation number in the subject line and the UEI in the body, with no physical or portal submissions accepted. Invoicing is mandated through the Treasury’s Invoice Processing Platform, and the contractor is responsible for all damage incurred during receipt, storage, and work phases, with vehicles prohibited from overnight outdoor storage. The contract includes a 12-month warranty on all work and requires that manufacturer warranties be passed through to the government. Installation must not compromise OEM vehicle systems, and all wiring must be protected with weatherproof sheathing, shrink wrap, and sleeving to endure environmental extremes. The place of performance for upfitting is the vendor’s facility, while delivery must be made to the FWS San Luis NWR in Los Banos
