Well if you have blue seats, I don't think the body colour interior would look good at all with them, because you have two different shades of blue. If you want the blue leather, I think it automatically means you don't want the body interior, unless for some reason you wanted a red or yellow dash and blue seats... not my idea of a good combo.

Personally, I think the car appealing to good taste is most important for resale when deciding on colours. You don't want someone to come see it, and go 'ugh, why did you order it that way' Beyond that, I wouldn't say its a big deal.
