Law Farm is more like a mix of a police department and a base for community's police officers. Since players can respawn there, having the ability to instantly repair their vehicles and refuel them would make it a bit unfair for L9 groups. L9 groups can refuel and repair their vehicles inside their bases. Indeed there would be a payment inside law Farm but still this feature would provide the whole police team with the comfort of respawning at a place where you can instantly gain access to your broken vehicle again, which I think should stay as a "L9 group feature" as it is an award for their contribution in the community. I'm not completely negative on this one however, since a big difference is that players will pay whereas L9 groups don't. I'm neutral for now.
Positive This would be of great use for many cops indeed as a lot of them don't have neither DL or repair kit/jerry cans to fix/refuel their veh when they spawn their after an AR or something similar and as mentioned already CV does have a repair point, it does not have a gas station tho if added both to law farm I see no probleam adding a gas station to CV too.
