well, since you DO have a pretty car, w/a really pretty interior, you should get the prettiest tank as well, though i really think there are cooler gadgets to get. for eg: full monty tire temp gauge, does 3 readings on each corner w/ full display and memory... actually usefull too! (takes up much less space
)
esp since you don't have a cage to climb over, driving for air can't be *that* bad.
