Regarding the case, it's the only one we have that fits a Relay board currently, you could always spray the top black!
You could use a UPS to monitor the voltage?

Obviously if the engines on, then Pi goes on, but if engine is off then Pi would turn off.
Not sure whether they'll both fit in that box, you might need to get something bigger like a Fibox and just drill holes where you need them.
I would also suggest that you don't just switch the system off without following a proper shutdown procedure. You'll quickly destroy your SD card!
