Wow this is an amazing find. Thank you. Do you have more pictures of unmarked LASD units, by any chance. Now that you've given me those pictures, I might as well make 2 or maybe 3 unmarked sheriff units.
I have been doing testing with the prototype setup ingame. I've decided to go with having an incomplete lineup of leaving behind vanilla assets. The main reason for this decision is due to the prototypes. It would be impractical for me to make 2 versions of this mod, one with many color variants, and another with unique vehicles per prototype.
I can share some good news: all civilian vehicles (so far) implemented into the game have wheels. The next few days will be finishing up textures and models for the remaining 4 vehicles I've not completed, and to start the civilian lighting on the cars.
