This is probably not a very good suggestion but:

I feel like high up police ranks should have something like this:
One car per life, when you get out of the car it despawns.

And for only ranks above SWAT Sniper or something.

I feel like instead you should have to buy like a jaros door hack so you dont have to grind cop so much.

Then it would crash the server because of too many cars.
