Was discussing with Ray in VIP voice and decided to make a suggestion.
The ability to either select a livery number when you call for example an ambulance or air ambulance
Or the ability to either have a chance at 2 different models, with a % chance of one or the other. Or the ability to have a specific vehicle for that area attend. So north of the map you could have a Blaine county ems. and when south you get a Los Santos ems
