poll; body color under car or chassis black?

My challenger is my show car and is perfect.
I painted the underside in gloss black so it would be easy to clean yet still be forgiving in those hard to get at areas.
Yes,I do clean it underneath and yes,I do drive it but not much.
I get really p!ssed off when I get caught out in the rain with it because it's not a pleasant job cleaning underneath.
