I've recently started working on a (hopefully) quick and simple project, an unmarked 2008 Ford Crown Victoria, featuring Hanako's CVPI base and Kane104's Talons:
Most of the equipment is set up as extras, it is possible to use for example it as a detective vehicle with minimal equipment, or as an unmarked traffic patrol car with a laptop, radars, a partition and a pushbar.
I'm currently working on a Whelen SA315P siren and Cencom Gold controller.
