I had a Ford that was black with black interior, and a white headliner. I didn't even notice it was white until I had to decide which headliner to get on an Audi. Audi is black with black with black headliner, and I can't say that it feels gloomy inside.
About to buy another Audi, and this one is black with black and has a white headliner. I am concerned about it. My kids never put handprints on the Ford, but I did have a big black handprint from the oil-change guy grabbing it while putting the little sticker at the top of the windshield.
Reading here makes me feel better about this next car coming with white, since at least half the people prefer it.
