I have a 2002 GS430 and I love the V8!! Period!!
My MPG averages are 22-23 around town with an average speed of 36 MPH, and when I drove the car from Boston to S. Carolina....I got 27 MPG per the on board navigation computer.
I agree with what was stated about the .5 delay with the gas pedal...the "drive by wire" does have a delay, but when you step on the gas...what a great sensation!!!
I Fear no one!! (luxury sedans that is) B)
