I'm planning to order a DS HSE next week, but I have a couple questions for you veterans. First, in another thread someone mentioned waiting to order a 2018 model for the Ingenium engine. Can anyone tell me more about that? Second, I'm definitely getting the Alpine White exterior but I'm unsure about the interior. I like the look of the almond interior, but apparently most people go with black. Can you almond-interior-owners tell me if blue jeans stain the seats? (A common complaint online about beige interiors in general.) Do you regret going with the lighter interior?
