I assume you don’t have kids (if you’re gonna go with white). If you Ceramic coat the interior, it really helps with spills and stains.
Both would be good. I think tan looks better with dark greys. But I love tan leather and was going to get it with a Loire blue RRS. I think for blue exterior, you should go with white. Such a timeless combo, white with blue!
I had white leather in my first SVR, even with coating with a ceramic coating it was still a once a week process to wipe the door panel, handles, drivers seat, steering wheel from dust, dirt or jean or belt dye. Yes the ceramic coating ( I applied Gyeon Leather & fabric shield to all my vehicles since the SVR purchase) it works & helps... but it doesn't 100% protect the surfaces from dirt of staining. You still have to do maintain cleaning & proper leather care.
decided to order ATB....When the dealer took out all the factory covers , I wasn't impressed with the leather quality on the door panels, dashboard and lot of hard plastic in the centre console, saw few wrinkle spots in the back seats. I asked him if he would order a ATB for me and he gladly accepted my request.
