These customized Mustangs typically feature:
* Dark Highland Green (or a very similar dark green) paint: This is the signature color of McQueen's car.
* Minimal badging: The Bullitt Mustangs in the movie were relatively understated, lacking excessive chrome or exterior branding.
* Specific wheels: Often, replicas of the wheels seen on the movie car are used.
* Performance upgrades: Many owners upgrade the engine and other performance aspects to reflect the powerful nature of the movie car.
While Ford has released special edition "Bullitt" Mustangs (like in 2001 and 2008, and more recently), these are factory-produced cars with specific features, not simply any dark green Mustang. The term "Bullitt Mustang" is more broadly used to describe any Mustang modified to look like McQueen's car.
