A rare civilian-converted AM General M1123 HMMWV has surfaced for sale on Hagerty Marketplace, listed out of Peoria, Arizona. It joins a run of unusual auction finds Motorious has tracked recently, including a no-reserve 1973 Chevrolet Camaro Z/28 that also crossed the block through Hagerty. Bidding on this ex-military Humvee currently sits at $5,250, with the auction scheduled to close on July 21.The HMMWV family got its start in 1985, when AM General began supplying the type to the U.S. military as a replacement for the aging Jeep-based light trucks of the Vietnam era. Its reputation for durability was cemented during the 1991 Gulf War, and by 1992 AM General began selling civilian versions, eventually partnering with General Motors to help market the trucks to private buyers. Many of the Humvees available today started life as surplus military trucks before being converted for street use, which is exactly the path this M1123 has taken.This particular truck wears a slant-back hardtop and rigid X-frame doors, both hallmarks of the civilian conversion process. Power comes from the factory 6.5-liter diesel V8, routed to all four wheels through a four-speed automatic transmission, a dual-range transfer case, portal axles, and limited-slip differentials, hardware originally engineered to shrug off far more punishment than any street truck will ever see. Inboard disc brakes and 16.5-inch, 12-bolt beadlock steel wheels round out the running gear inherited from its military roots.Photo: Hagerty MarketplaceOutside, the body is finished in a gray rubberized bedliner coating and fitted with a fold-down brush guard, a rear step bumper, sliding side windows, and a five-window slant-back roofline. The factory-style lighting has been upgraded throughout, with LED headlights and indicators up front and integrated auxiliary lighting front and rear, useful upgrades for a truck that spends as much time off pavement as on it.AdvertisementAdvertisementThe cabin has been just as thoroughly reworked. Four Smittybilt bucket seats trimmed in black vinyl flank a fabricated center console with built-in storage and cupholders, while the entire electrical system has been converted to a 12-volt setup that powers USB outlets, auxiliary switches, and a Bluetooth receiver wired into a set of Pioneer speakers. It is a setup that trades zero off-road capability for a genuinely usable daily interior.Photo: Hagerty MarketplaceThe current seller has owned this M1123 since October 2022 and holds a clean Arizona title in their name that lists it as a 2000 model, matching the January 2000 delivery date stamped on the identification tag. Recent maintenance includes a replaced fuel pump, drive belt, and air filter, and the seller notes only one real cosmetic flaw: some wear showing on the interior trim. The odometer shows roughly 20,000 miles, marked TMU (too many/mileage unknown), which is typical for a truck with a military service history that predates its civilian paperwork.Photo: Hagerty MarketplacePhotos and listing details for this M1123 come courtesy of Hagerty Marketplace, where bidding remains open through July 21.
