This is the Kuruma model from Manhunt 2, Although it looks similar to the Kuruma people from the discussion topic on this mods conversion felt that the name ExSess was better suited to the model to make it something different since there is no official word that the car in Manhunt 2 is a Kuruma, it has only been assumed to be one due to its likeness to the model from GTA III.
Available in MVL Format for Vice City so you add a new Vehicle without Replacing.
GTA III version available to replace the Kuruma, for some reason the smoothing on the reflection map is bugging.
