Pros:
Nobody wants to tailgate you.
Nobody wants to borrow your car.
Nobody will car jack you as you can chase them down on foot (85 on back diesels!)

Cons:
Black light syndrome (yes I get on my TD after long trips).
You must buy your diesel fuel were they sell alot of it or else you will get water in your tank.
You can't sneak in late at night as your wife will hear you pull in the driveway.
