IMHO, anything that is "period correct" is fine with me. I regret removing the "cigar box" snorkel hood scoop that came on my car when I bought it. http://mmb.maverick.to/gallery/showimage.php?i=1311&original=1&c=favorites
I like them on my Comet. Of course they say "Cooper Cobra GT". Might have something to do with my name.....LOL
Maverick's do not conform to what is "IN" I personally like them black in the front and white in the rear.
I prefer white letters out. Only problem is, most of the new vehicles have tires with such small sidewalls that there isn't even room for white letters, to be able to read them, they'd have to extend into the tread. I prefer the old style, 15" tires with white letters myself, instead of mostly shiny rim with micro sized black sidewalls, but I'm an old fart and I'm sticking with it.
black wall, please... Next we will want some side pipes and chain steering wheels. lol But in then end, it is your car.
