i'd personally keep the X5, granted Im' a newbie - the Acura Honda products have some extremely high maintenance, such as the freakin VTM fluid change and constant worry about tranny and other oils. Great cars but the new designs are also a fail. They are too fragile esp the 4wd/awd versions. My wife has a Pilot, which is the same as an acura mdx but different body - and we love it except the maintenance every few thousand miles sux.
