MC - Hmmm - good point about the red paint fading - I hadn't thought of that.
In that case, maybe I'd go for a natty, but a bit faded, combination of black & white instead. I could then affix an oversized public address loud speaker to the roof & write “serve and protect” down the side. Might not be too aerodynamic, but at least I’d be able to blast out “Stand by your Man” as I go by.
