Popular Hot Rodding, it's on the front page, of their web page, lower left had side. I haven't seen it on paper, just online. Someone posted a link to it a few weeks ago. http://www.popularhotrodding.com/features/1309_1974_ford_maverick/
My guess is that to recreate that depth without photo shoot effects, one would almost need some sort of pearlescent over coat on top of the standard mineral gray
Look at the shadows in the background, then look at the ones from the car...one is one way, and the other is opposite..
Regardless of the light source, that is a really nice color. I will need to look up the ford from 01 and see if it looks the same.
