Revised livery, applied corrections to font inclination and changed position of unit number. Added nypd insignia in front. Remember this is not the model that nypd uses, so until a modder creates a bearcat I can't do better than that. If you want also a nypd version for the insurgent (since it supports multiple liveries) tell me in the comments.

Credits go to Yard1 and POLICESCO.
PS: I found out that if I use the riot+hi.ytd file, the game crashes. So it's best to put only the 3 riot files without the 4th one (riot+hi.ytd).
 
I suggest you use the swat model made by dualift for nypd esu:

Both textures come in 4096x4096 and 2048x2048 resolution.
Installation:
Replace the "tahoe_skin" inside tahoe.ytd and tahoe+hi.ytd with a texture from my pack (use the Replace button). The car doesn't support multiple liveries so there's only one version for each department.
Known bugs:
- Small areas of white paint on both side mirrors and on the right front wing. Feel free to try and find out which pixels are responsible because I gave up after one hour and 5 game restarts.
