Back in March 2024, GM Authority reported that Flat Out Autos‘ #3 GMC Jimmy conversion was posted for sale for a little under $150,000. Now, just a few months later, the same converted GMC Sierra 1500 is headed to auction in Pennsylvania.
Listed on Mecum Auctions, this Jimmy will be crossing the block on Saturday July 27th. Of course, this particular build has been posted for sale numerous times already, including on Bring a Trailer.
It’s worth noting that this unit was on display at SEMA 2023.
In regard to how this GMC Jimmy came to be, Flat Out Autos begins the conversion with a Sierra Regular Cab pickup truck and shortens the frame, cuts out the back of the cabin to expose it to the bed, and installs a roll bar and bench seat behind the front seats. This particular off-road-oriented SUV build is painted in Porsche Chalk Gray and is underscored by custom Jimmy badging throughout. The bed cap is color-matched to the body, and features tinted glass and an integrated rear hatch with a power lock. Additional bits and bobs include LED headlights, red front recovery hooks, AT4 badging, a receiver hitch, a MultiPro tailgate, and quad exhaust tips.
As for rollers, this Jimmy rides on custom black-finished 22-inch Rotiform wheels wrapped in 285/50R22 Nitto Ridge Grappler rubber. Fox shocks and BDS front upper control arms allow for the lifted look, while four-wheel anti-lock disc brakes deliver all the stopping power.
Moving to the interior, the heated and ventilated front bucket seats are upholstered in a blue leather colorway, a color scheme that continues into the dash, center console, doors, and side panels. Creature comforts include a wireless cell phone charger, air conditioning, cruise control, and Apple CarPlay/Android Auto connectivity. Out back, a power-folding rear bench seat can be found, along with a carpeted cargo area floor.
Under the hood lies the naturally aspirated 5.3L V8 L84 gasoline engine, which produces 355 horsepower and 383 pound-feet of torque in the Sierra. This output is directed to all four wheels through the GM 10-speed automatic transmission.
Interestingly, General Motors actually had plans to revive the GMC Jimmy in response to the Ford Bronco. However, The General ultimately decided to cancel the project.

The Jimmy is a no brainer built with an existing platform, full size wouldn’t have any direct competition. I had a 98 GMC Yukon 2 dr with barn doors in back, I should have kept it. GM missed the mark on a great opportunity, it’s obvious when Broncos and Wranglers are so popular. If it were factory built the price would be affordable, these aftermarket units will never sell enough to make it worth the trouble.
A great way to sh*t on the Bronco is to bring back the Jimmy / real Blazer!
