I would suggest to remake the available cars in the game and using texture mods, to make them looking authentic to how they looked in the BETA stage of Driv3r.
Here are some ideas of mine - Beta Nice Police skin, PS2 and XBOX traffic remakes. Also, there will be vehicle remakes outside Driv3r.
PD right suggested different Miami PD car. Max thunder suggested the beta Mustang (very nice idea!). I started remaking few of the textures, and hopefully there will be some progress soon
Here are few images showing some stuff:
That 2CV was too much sex machine, why the hell Reflections removed it...
