Just traded in a 2007 MB CLS550 for a more practical vehicle... no regrets! This minivan is more useful and spacious than our MB GL450. Touring model wonderful in that no options apply (comes fully loaded); avoid the PAX system however - expensive to replace the tires. Sound system/DVD player/navigation system are user friendly. Cylinder deactivation of 3.5L V6 is great, enabling 26 mpg on highway. Amount of storage space (without folding 3rd row seats flat) is astonishing. I highly recommend this vehicle to anyone with kids and dogs (we have one child and 2 dogs).
Sound system/navigation/DVD player; cylinder deactivation system; storage space -- EVERYTHING!
Power folding 3rd row seats (although very easy to manually adjust).
