I drive pretty "aggressive", leave it in too low a gear most of the time and usually exceed the speed limits by "the allowable margins". Only the day we drove it home from the dealer 200 miles away did I record 26mpg (at mostly 75-80 mph). I'm waiting until we take a real trip, like to HC 2001, to see if I can get decent mileage. BTW, how do you like your new wheels? Did Tirerack come through with everything they said they would (betting "yes" on this...)? They look good, but I still have BMW pads on the 99 and would just go nuts if I had to clean twice as many/smaller spokes :)) How have they effected the ride or handling? Have you noticed any change in acceleration due to the mass? Just curious... Take care, Randy
