Maybe the 6-wagon died as the 5 picked up sales? Would be great if they got the 6 cyl into the 5. The fuel economy in real world driving would likely not be much different than the 6-wagon is/was, but would improve drivability immensely.
The 3.0 in the MPV moves much more spritely with all it's bulk than the 2.3 in my more diminutive 5.
Or...a torquey diesel.
PS, BIG fan of the test driving the more baseline vehicles!
