Is that a personal preference thing, or due to technical up-keepings of the types of paint? I always thought flat colors like AW and Jet Black were easier to maintain in terms of hiding defects more (though not sure about that) and being easier to paint match if need be, or touch up (pretty sure about that.... ?).
My only problem with AW or any flat white in general is that they've become soooo popular, they're starting to lose their "pop" to me. I.e starting to give me that dreaded "Delivery Van/Refrigerator/Appliance look, like a blank canvas. That said, I will always strongly consider a flat white when I car shop.
My previous 2 cars were Mercedes Arctic Whites, which are more creamy than Alpine White, and they both started getting more yellowy-creamy after just a year, which made me weary of whites in general (in Europe you see many M-B Taxi's that are obviously not well cared for, yet still pretty new, with Arctic Whites that have turned so yellow you'd almost think it was a different color).
