"Paint it black, you devils!"
I love black cars, but they do have two drawbacks. First, black on an old car (or any new car for that matter) highlights any flaws in body panel alignments, gaps, and you pretty much have to have perfectly smooth panels. Black paint is expensive, and going to the expense of making the body perfect adds to the cost. The second drawback is keeping it clean and not inducing swirl marks. Swirls show up extremely well on black cars in bright sunlight. One trick that was relayed to me was to always use a drying cloth with motions that correspond to the wind direction that the car would experience: on the hood that means fore and aft only. Never clean the hood with a sideways or circular motion.
All that said, black, when done right, is absolutely a show stopper. Black Paint Matters!
Black paint is highly reflective as well, so I'd recommend that you think about a matte finish for the hood so you can avoid blinding reflective sunlight in your eyes.
