So 300SDLs do 70mph at 3,000rpm? Wow... must be a lot more quiet on the highways than the 617s. 300SDs do 65mph at 3,000rpm. That has to be one aspect of this car I hate, truly hate. The highway noise. Lately, I've been playing book CDs and listening to some music during long trips in the 300SD and those make it impossible for me to even hear the noise of the engine, but when I decide to turn off all sorts of music for some peace, I wish I never sold my Toyota Avalon. Oh well.
