this sound *BLEEP*es me off greatly! you'd think that for the $37,000 i paid for my new IS250, i would get a silent engine...i also own a 2003 Nissan Altima that is as quiet as a mouse when running....if Nissan can produce an engine that's quiet, why can't Lexus? I'm tired of friends asking me what that ticking is and looking at me like I'm crazy when I explain that it's "normal"....lexus needs to fix this or i'll be buying a BMW next time!
