There are some issues with the first release of Highguys, which was created from a 3D model to an in-game, however there are plans for future improvements. - Selectable color choices- Body Chute (for drag mode)
Interior Trim Valance: Grill
-A variety of engine choices- stock 4.8L 0-60 in around 5.3 seconds and 5.0L 0-60 in roughly 3.5 seconds
Drag Tune Fast, hehe
And there are still a ton of features to choose from.
