For what my friend above stated I agreee... but call me crazy because the sport suspension is the only way I drive! My custom mode is comfort engine, sport everything else. Only because I love love love the sport steering.. my comfort mode is never used as I mainly go between sport and custom. I did use eco and smart but saw better mpg (with my driving style) with comfort mode. And back to the start, I do not like the soft over-sensitive comfort mode steering so bam custom mode saves.
