This 1989 Isuzu Trooper RS 4×4 is offered for $13,500 with just under 56,000 original miles, located in Annapolis, Maryland. A rare two-door RS with a short wheelbase and true body-on-frame construction, this example pairs real off-road capability with unusually deep documentation curated through
The Common Gear. The result is a Trooper that can be evaluated with confidence, even from a distance, thanks to a
clear, organized record of its restoration and ongoing care.
- Rare RS Configuration: The two-door Isuzu Trooper RS was produced in very limited numbers for the U.S. market, combining a short-wheelbase body, RS-specific trim, and off-road-focused configuration that made it a niche enthusiast model even when new, and genuinely scarce today in documented, low-mileage condition.
- Proven Powertrain: Power comes from the fuel-injected 2.6L inline 4-cylinder paired with the desirable Aisin automatic transmission. A dual-range transfer case engages 4×4 cleanly, delivering strong low-speed control and dependable traction when conditions demand it.
- Extensively Addressed Exterior & Chassis: While much of the exterior retains its original paint, this Trooper has undergone documented rust mitigation and metal repair to address common Northeast wear, with records detailing the work performed to stabilize and preserve the body and undercarriage. Upgrades include General Grabber A/T tires and Hella auxiliary front lights, while cosmetic patina such as roof wear from long-term rack use and a localized clearcoat blemish on the hood were intentionally left intact to prioritize authenticity over cosmetic over-restoration.
- RS-Specific Interior & Spares: The RS is equipped with a factory black interior, giving it a more purposeful, driver-focused feel. Included in the sale is a substantial collection of RS-specific spare interior components like the dash, door panels, and carpets, along with additional parts accumulated over years of careful ownership.
- Documented History, Clean Title: This Trooper shows genuine mileage and carries a clean Maryland title in the seller’s name. Its ownership, mileage consistency, and mechanical stewardship are supported by thorough records rather than assumptions.
Documentation, Stewardship & Market Context
What meaningfully sets this Trooper RS apart is not just the work performed, but how thoroughly it has been documented. Maintenance, projects, and receipts have been organized to provide a fully vetted view of the vehicle, allowing prospective buyers to understand its condition and history without relying on guesswork. This approach reflects a philosophy of ownership rooted in transparency and long-term stewardship rather than short-term presentation.
That same mindset underpins
The Common Gear, which exists to help owners document builds, restorations, and long-term projects at this same level, whether they choose to manage the records themselves or opt for a more hands-on, white-glove approach for large paper trails or collections. In a market where many vintage 4×4s trade hands with vague histories, this Trooper RS stands out as a well-documented, confidently represented example.
From a broader market standpoint, early Isuzu Troopers, particularly two-door RS models, are gaining renewed attention as enthusiasts seek out analog, mechanically simple 4×4s with genuine global off-road pedigree. With its low mileage, original character, and comprehensive documentation, this RS represents a shrinking segment of the market that will be increasingly hard to replicate.
