1990 AM General M998 — Former SC Highway Patrol • Helmet-Top 4-Door • 29k Miles • Fully Serviced
This 1990 AM General M998 is a genuine U.S. military Humvee that later served the South Carolina Highway Patrol before being released through SC State Surplus Property. It comes with a clean, street-legal South Carolina title and is stored in our Aiken, SC climate-controlled showroom. The vehicle shown is owned, maintained, and driven by us here at Car Cave USA.
Presented in a deep navy military finish, this M998 wears its correct helmet-top enclosure, four full soft doors, and dual side storage compartments. This configuration is far more usable than the typical soft-top/troop carrier layout and provides secure cargo capacity while retaining the rugged character of the original aluminum-bodied Humvee.
Power comes from the trusted 6.2L GM Detroit Diesel V8 paired with a 3-speed automatic and full-time 4WD through the NP218 transfer case. The wide-track stance, portal-style geared hubs, and high ground clearance give the M998 its legendary off-road capability. This example has just 29,300 miles and drives exactly as a well-maintained Humvee should—mechanically honest, durable, and ready for work or recreation.
This M998 recently received comprehensive service at Car Cave USA, including a new fan clutch, glow plug system overhaul, new batteries, ignition upgrades, and fresh filters and fluids. Over $5,200 in mechanical work was completed to bring the truck to proper standards (see service file).
With military provenance, excellent structure, and fresh maintenance, this is a clean, turnkey M998 ready for a ranch, collection, hunting property, or off-road use.
