I had thought that it was a wash driving the X with its 15-17mpg and 87 octane VS driving the S2000 at 25mpg and 93 octane (required) - but I ran the numbers and I actually save a fair amount by driving the Honda (though it hurts that much more to have to buy that premium gas )

Would be stupid to get rid of it (the X), though... it's almost paid off.

And I wouldn't anyway... love it too much and have put too much into mods.
