My inlaws are looking to add to the fleet and my they love the throttle response of their '06 S60 2.5T. The lower spooling rpm turbo can't be beat, at least to them. Now they've been looking at a larger vehicle for hauling stuff. They've owned bricks since '73 and would like to convince them to get an XC 90.<p>Anyway, can anyone give me a brief comparison of the XC90 and the X-3/5's in terms of MPG, comfort, cargo capacity and throttle response. Which ever they go with, they won't buy the 8 cylinder version.
