We are in the process of selecting a 2018 or 2019 S90. We live in Florida so we are trying to avoid the black leather interior or "charcoal" as Volvo calls it for heat build-up reasons. I can't say we care much for the amber color and that leaves the off white which Volvo calls "Blond" or the brown interior. We like the way the Blond looks but are worried about how difficult it is to maintain and keep clean. Does anyone have any words of wisdom regarding this topic? Just how difficult is the Blond interior leather to keep it looking good?
