White with black interior looks better, but that's my opinion, otherwise the inside of the car looks to bright.
If you are going to tint your windows, it softens that white / white bright look and looks really good. The issue with me on white Teslas is simply that it was the free color for a while, so there are way way waaaaayyyy too many of them in "high density Tesla" areas like CA is.
As for white interior upkeep, I dont have it, but many people do and love it. We also have long, long threads (at least a couple) on "removing stains from white seats". I think the white interior looks better but I dont like doing any real upkeep on the interior (empty nester, usually drive my model 3 performance alone since when I go somewhere with my wife we take her model Y P).
I also wear jeans almost every day, but simple ones (Levis), not high end super dyed jeans. Anyway, there is a thread on removing stains from white seats in the model 3 subforum, interested peeps could search for it as I am just letting interested people know, not trying to rain on white seat parade).
I dont like red cars usually at all, and many of the pics of ultra red makes me think thats what I would have ordered. Its also likely to be rare at least for a while on model 3Ps so there is that too, for those who enjoy that (well, as rare as a Tesla model 3 can be, which is "not very", lol).
