Someone ought to do an experiment to actually test this theory - I'd think it's pretty simple to set up. Identical cars except for interior, park them next to each other, put thermometers in the same place in both.
Tan (or sand or beige) is hard to keep pristine - the parts where you touch it get darker over time (that's dirt, not patina
) even if you are careful and never stain it. Even if you think yours is nice looking, have it professionally detailed and you'll be surprised at the difference
Black absorbs more heat than any other color. This is basic physics. Now granted any car's interior will absorb heat in a hot sun, but black will always absorb more. Touch a white car in the sun vs a black car. The white car is noticeably cooler. Interiors suffer from the greenhouse effect, they will all get hot but black will always be hotter.
I try and remember to crack the sunroof, it makes a big difference.
