While waiting for my dealer to locate a fully loaded 3.0 quartz/charcoal sport, I'm wondering will the Arden body & suspension parts replace or supplement the various componets that are part of the sport package? In other words, am I better off getting the "regular" x-type if my ultimate goal is to use some Arden accessories? Just not familar with Arden on the west side of the pond and don't want to pay twice for the same thing.
