I just got GTA 2 a while back and since I couldn't find many car mods for it, I made my own. They are based on vehicles from GTA IV and V like the new Patriot, Bison, Cheetah, Infernus, etc.
Here's a screenshot:
I also made some weapon HUD replacements:
Most of the images are taken from the GTA Wikia and edited by me.
They are all inside the same file but separated by car and weapons inside it, with readmes that say how to instal them (hopefully I didn't make mistakes in it or put the wrong pictures, if so tell me).
I hope you like them!
EDIT: I think I made a mistake in the Sprunk truck's readme, you may need to do the following to install it properly:
-Import the truck using the palette I specified.
-Double click on the sprite, you see the colors are all weird or it reverts back to the old truck in a different color.
-Then you import it again and click on "leave the palettes alone". Now it should work.
