While some might argue that classic Ford Broncos are best left stock, others would appreciate one that’s punchier and boasts a few upgrades meant to enhance its rock-crawling ability.

If agree with the latter, then you will probably fall for this 1972 custom-built example that is on its way to auction.

Commissioned by a Shelby collector, it rocks a 331-cubic-inch V8 with a Holley four-barrel carburetor. Built by Shelby, the mill kicks out 421 HP and is mated to a five-speed manual transmission with a transfer case and four-wheel drive.

The off-roader was fully refurbished and detailed, as you can see in the comprehensive image gallery. It sports a blue paint finish on top of the black and blue interior, has a set of Fuelie wheels wrapped in chunky off-road rubber, steel bumpers, fender flares, a winch, roll cage, heavy-duty suspension and lift kit. It also features a tilt steering column, comfortable front seats and a digital gauge cluster, among others.

Since completion, this 1972 Bronco is said to have been driven for less than 300 miles (483 km). It will be auctioned off by RMSothebys on January 22, at their Arizona event that will be streamed live, and is estimated to fetch between $120,000 and $160,000, or more than four times the starting price of the all-new 2021 Bronco.
