Commercial and Fleet Vehicle Repair Services....or something to that nature...
I was actually just thinking of a spot somewhere on the map where cops can take their beat up cars and maybe do a /repaircar to get the car fixed for a small fee.
I think this would be beneficial for a few reasons. Police vehicles take more punishment then any vehicle on the road (in game and in real life), so naturally they need a place to go to get repairs and maintenance. After a long pursuit, if a suspect manages to get away they can visit their local pay'nspray and make their vehicle 100% functional again, while the cops are stuck with a smoking, rattling mess.
If cops could repair their own cars, I believe the admins would get much fewer requests for car respawns. The problem is, when a cops car gets damaged, they go drop it off at the PD and get a new one, leaving the junker behind for the next cop that goes on duty. Eventually all the cop cars on the server are scattered around the map broken down.
Keep our police force's efficiency 100%
