Just when you thought RDJ couldn't get any cooler.

Robert Downey Jr. has established himself as the king of cool around Hollywood. From characters like Ironman and Sherlock Holmes to his natural confidence, bravado, and impressive watch collection, RDJ is a classic guy's guy. Now he's cemented this title by indulging in one of the most sensational custom Mustangs we've had the pleasure of laying eyes upon.

The car is much more than the pretty face you can see here, featuring a 5.0 supercharged V8 that's said to possess roughly 800 hp, and a Bowler T56 6-speed manual gearbox. The original car was premiered in 2017 after some serious refurbishment to both the exterior and interior. 

The inside is as majestic as the exterior and comes courtesy of California's own Gabe's Custom Interiors. Classic brown leather is accentuated by some pure white and masculine greys, which further define the car's classic brash character. Beyond this, a new steering wheel was a given restoration, alongside a skeletal gearstick, and bucket seats.
