Foolish to decide on a drivetrain based on cost of fuel...

You are buying a $70k car- cents per mile should not be a top 10 criteria, IMO

HOWEVER, IMO the Diesel is a better driving car than the 3L gas...much more torque. Just a brute moving along freeways, up and down hills, etc. Better driveability than the smaller gas in terms of revving, up/down shifting,
