One of my current WIP's, based on the livery used by the Wayne, Michigan police force.
Preliminary list of supported cars:
CVPI, old Charger, new-shape Impala ('06-'12 model), Tahoe (KevinDV's model, NOT the Luxart model), Vapid Speedo (by Scyattica, released unlocked, have a got at making variations).
Release date unknown.
