I do see an awful lot of posts on Reddit that are like -- Omg how do I clean these white seats? My gf wore a dress and now they are stained, etc..
Glad with my choice of black
I saw an equal mix of those posts you mention above here, along with statements that people have made in this thread, like "I have had them for X time and other than doing X, they look like new". What I never saw, however, was anyone with black seats saying anything about upkeep on them.
I bought the black seats. My Model 3 is Blue exterior, and I really liked the look of blue exterior / white interior, but knew that I am NOT a person who is "into detailing cars". Its not like I am a slob or something, I dont eat in the car, etc, I just dont spend a bunch of time cleaning my car.
I have had my car since Dec of 2018 with black seats, and they still look virtually brand new, and the only cleaning I have done to them is to wipe them down with a microfiber cloth maybe 4-5 times (total, since december of 2018).
Its all personal choice as mentioned, but there is no way in heck I would change an order, lose an assigned vin and go back into the queue, AND pay 2k more (1k seats + 1k price increase) for white seats. Still, you are going to find more cars with a "safe" interior like the black one is, so if you want something that stands out more, get the white.
