I tried this, and looked at what you've got in your signature, but the car I've put in doesn't seem to have any vehicle audio. When I drive around there's no engine sound, nor is there any door opening/closing noise, etc. Siren works, though.
How would you go about making more police slots? I used to use the Police and EMS Vehicles as Addons pack but it hasn't been updated in a while to support all the new ELS models coming out, and I too am running out of space, since I like to have 5 different agencies in my game 0.0
Awesome! Can't wait. I do agree with you though, the '14 FPIU looks better, however I use the '16 one cuz I prefer to have an all ELS setup. I did, however, install that '14 FPIU as an addon vehicle just to drive around with these skins :D
