The High-End Exotic is heavily based on the 2004 Ford Mustang GTR Concept. It reads "Caballo" (spanish for a male horse) on the rear bumper.
A red version of this vehicle, without the performance trim, did exist during development of the game. It was removed from the final version of State of Decay, but added back with Year One Survival Edition.
The High-End Exotic accelerates rapidly and can reach high top speeds even without a boost in seconds flat. However, it is a fragile vehicle and has sensitive handling, so inexperienced players are likely to wreck it if they are not careful.
