I think the intent is for a very basic low tech look.
But...
I think a nice powder coat gloss black finish would be very classy, something along the line of the Pioneer Elite.
Or, how 'bout a nice turned metal finish like the Trans Am dashboards of the 70s had? Smokey and The Bandit were Outlaws wern't they?
Sorry, got weird for a minute there.
