I vote you go with white interior for the following reasons: 1) I completely agree with those who have already posted that white with purple really pops; it does! And 2) It won't be a problem to keep clean unless you drive it every day, eat in it, spill in it, and never clean it. Then, yes, in a couple of years you will have a mess with a white interior. However, if you take care of it, that won't happen. Back in the 70s we had a 72 Camaro with white interior and a 73 Road Runner with white interior and both were very nice, especially the Road Runner which was root beer brown with white stripes to match the white interior. Just like the purple and white combination mentioned above, it was gorgeous and really popped.
