When the balla is driving his car, he disappears and the car turn black to kill you. But don't get the car to touch you or else it will blow up on you and the laugh will appear when it's destroyed, and there the creepy music playing in the car.
There's 3 types of ghost cars in v2.0.
Type "crap" Huntley
Type "mario" Kart
Type "oops" Bike (Plays Weegee)
For v1.0, the strange glitch when you blow up a car with a mini-gun, somehow the engine is still running and still gets you in 3-wheels like this car is a terminator.
