Made 3 skins, here are the screenshots:
The actual skins should be attached to this post. I've linked the models, which are not made by me:
Slicktop Taurus
Tahoe & CVPI
Unfortunately, I'm on a very limited schedule and will be leaving the country tomorrow, and won't have internet access for at least a month, so I couldn't fill your other requests. Maybe when I return I'll do a whole makeover of the LCPD to the CCPD.
Good luck getting into the police academy!!!
