Police cars require monthly oil changes or more due to the constant idling of the vehicles.
This costs us $79 per change plus the time to drive it there and someone to pick it up a power hours). Granted it's only 10 minutes each way but that's 40 minutes of time (20 for drop off guy and 20 for pickup guy).
That equates to roughly $960 per year. This doesn't factor in any other maintenance but everything else should be relatively the same.
I'd say a $25,000 equinox ev would be a nice option for many departments. That's what they cost after rebates and probably with fleet discounts so it's cheaper than the explorers you see in most departments.
