maintenance garage

As this was mentioned yesterday, I'll give my response again.

Keep in mind this is an emergency dispatching game. You can simulate vehicles going in for maintenance themselves by putting them as state 6 if you wished to do something like that. Perhaps instead you could have a warehouse full of spares and swap them out once the vehicles reach a certain mileage and then swap them back after a period of time - that's up to you though.

I don't mind having apparatus making themselves status 6 and something indicates that it's broken down etc, but I don't really want to be managing maintenance every 2 seconds, hence why them putting themselves out of service then back in when they're ready works fine for me.
