37k-Mile 1999 GMC Sierra 1500 SLT Extended Cab Z71 4×4 at No Reserve

This 1999 GMC Sierra 1500 SLT Extended Cab 4×4 pickup is a Canadian-market example that was imported to the US in March 1999 and remained registered to the original owner in Washington through 2025. Finished in Pewter Metallic over Pewter leather, the truck is powered by a 5.3-liter Vortec V8 linked to a four-speed automatic transmission, an Autotrac active dual-range transfer case, and a locking rear differential. Equipment includes the Z71 Off-Road Suspension Package, 17″ six-spoke cast-aluminum wheels, and running boards with integrated wheel arch flares in addition to heated power-adjustable front seats, air conditioning, cruise control, and a CD/cassette stereo. Purchased by the seller in January 2026, this GMT800 Sierra 1500 has 37k miles and is offered at no reserve with an owner’s manual, a clean Carfax report, and a clean Texas title in the seller’s name.

The truck is finished in Pewter Metallic and features a Wideside bed with Z71 decals and running boards with integrated wheel arch flares. Other details include a bug shield, fog lights, front tow hooks, a spray-in bedliner, and a receiver hitch. Photographs of paint meter readings, blemishes, and areas of touch-up paint are pictured in the gallery below. There is a sealed chip in the windshield.

The 17″ six-spoke cast-aluminum wheels are mounted with 265/75 Wild Country Trail 4SX tires. Off-road bump stops, 46mm shock absorbers, and stabilizer bars are fitted as part of the Z71 Off-Road Suspension Package, and stopping power is provided by disc brakes at all four corners.

The heated power-adjustable front captain’s chairs and rear bench are upholstered in Pewter leather, and interior amenities include a center console, an overhead console, a cassette stereo, a CD player, driver’s seat position memory settings, cruise control, air conditioning, and power windows, locks, and mirrors. There is some wear on the driver’s seat outer bolsters.

The leather-wrapped steering wheel frames a central 100-mph speedometer, a 6k-rpm tachometer, and gauges for fuel level, voltage, oil pressure, and coolant temperature. The digital odometer indicates 37k miles, approximately 250 of which were added under current ownership.

The 5.3-liter Vortec V8 was factory rated at 270 horsepower and 315 lb-ft of torque. The oil was changed in preparation for the sale.

Power is routed to the rear or all four wheels via a four-speed automatic transmission, an Autotrac active dual-range transfer case, and a locking rear differential with 4.10:1 gearing.

The Carfax report is free from accidents or other damage.
