The vinyl textures are just too hard to make out as they don't seem to follow any structural body layout at all. That, and all the cop cars apparently share the same texture, despite the different designs for each car. The only thing I could think of doing was replace the police badge logo with pony. Anything else will just screw up the the other cop cars that use the texture. Also, note the logo thingy I did at the background - that's probably the best thing I've ever edited, lol.

Oh well, have some obligatory extended MLP theme, because this video is obviously not pony enough. :|

If anyone else wants to try and mod this, TexMod is what I use.
