I dunno man - what's the 0-60 time on something like that? I really think it's around 25 seconds. Diesel IS more expensive than gas unless you use Premium, perhaps. You know it's a personal choice... I think you'll be able to enjoy the positives of owning it while putting up with the negatives just like with the VX. However, if you don't bite the bullet you may not let yourself live it down and you may come to view the VX differently.
P.S. - They get mileage that high because they don't go over 60 or 65mph - 45 going up hills...
