Now offered for sale on Bring a Trailer, this extensively reengineered 1988 Jeep Grand Wagoneer represents a no-compromise restoration and modernization project carried out by Function Drives Form of Carson City, Nevada. Originally registered in California and later Oregon, the iconic luxury SUV has undergone a comprehensive transformation since 2019, with documented build expenditures surpassing $150,000. The result is a highly refined classic 4×4 that blends vintage Jeep character with contemporary performance, reliability, and comfort.
At the heart of the build is a Cummins R2.8 Turbo Diesel crate engine, a sought-after modern powerplant renowned for its durability, efficiency, and low-end torque. Installed in 2020, the turbocharged 2.8-liter inline-four is paired with an advanced eight-speed automatic transmission equipped with a dedicated cooler package, delivering improved drivability and highway refinement compared with the factory setup.
Power is distributed through an Atlas transfer case and a set of robust Currie axles, creating a drivetrain engineered to handle both demanding off-road use and long-distance touring. Further mechanical attention was carried out in early 2026, when the differentials were rebuilt, rear axle shafts renewed, and the rear driveshaft professionally balanced.
The chassis and braking systems have received equally significant upgrades. The original 15-inch alloy wheels were stripped, straightened, and refinished during the restoration process, while a hydroboost-assisted braking system featuring Wilwood aluminum disc brakes at all four corners was added in 2020 to dramatically improve stopping performance. Ride quality was enhanced in 2022 through the installation of softer leaf springs, and additional maintenance performed in January 2026 included a rebuild of the left-side parking brake assembly.
Inside, the Grand Wagoneer has been elevated well beyond its factory luxury specifications. The cabin is trimmed in premium Katzkin Tuscany Palomino leather upholstery, complemented by distinctive plaid door-panel inserts and brushed-aluminum switchgear. Modern conveniences include Vintage Air climate control with integrated air conditioning and heating, keyless entry, a custom center console, and an electric parking brake. Entertainment is handled by a Continental Bluetooth head unit connected to a premium Hertz speaker system.
Driver-focused upgrades continue with a color-matched steering wheel mounted to a Flaming River steering column and a fully digital Dakota Digital instrument cluster. Together with the meticulously restored exterior, refinished bodywork, upgraded LED lighting, rechromed trim, and serviced roof-rack and windshield components, this Grand Wagoneer stands as an exceptional example of a classic American SUV reimagined for modern use without sacrificing its timeless appeal.
