This mod will spawn the SWAT Truck in traffic which only appear during the final mission "end of the line" and also the rare and sports cars will spawn frequently. :)
And car colors will not be your usual one. This is unique LOL XD

Replace files in your SA/data Folder :)
Enjoy!! :)
The cars used in the screenshots are BJ XL and Granger. Find them here at gtainside. :)
