Didn't Ford do a wagon with a V8 and RWD? Wasn't it called "Country Squire"? I'm waiting for the Taurus X with fake wood siding...
Myself, I'm waiting for the ecoboost version of the Flex. This is what I'm looking for to replace my 10-year-old Expy, but I want a little more torque. The T-X doesn't have enough room, otherwise it's a steal compared to the others in its class.
