This from Martin Nowak:

A few months back, I’ve shown Ambulance 812 with a black grill. Another North Palos Ambulance (802) drops the chrome grill for a black one. I believe these black grills fit their color scheme a lot better. I’ve never seen any other Ford E-series ambulance from the current generation with a black grill. Ambulance 802 is a 2010 Ford E-450/Osage. I also attached a recent picture of A812 along with Roberts Park Engine 32 and Ambulance 32.
