I present to you a pack of two Cheetahs. Modern from GTA III and more classic from GTA Vice City.
Both models were fitted with a mid-mounted engine.
The model from GTA III uses wheels from GTA LCS with a tread texture from SA, because. in terms of quality, this wheel is pretty close to GTA SA. Also this model was made with the help of my friend Gold (aka Stierlitz).
The model from GTA VC got pop-up headlights like the ZR-350 (there is a version without these headlights in the archive) and unique author's wheels.
