Gotcha! Vibrations must be very annoying, and they should be looking into more and try to fix it, cause I don't have it on my brand new Insight. In terms of the engine roar, it depends on the driving habit I'd say, it's still a very quiet car to be honest, when you turn on the engine, or driving at a lower speed, car makes this almost musical sound inside which is just seamless! However, when you try to accelerate and push the gas really hard (not floor but hard), then of course it makes the sound, and every car would make that sound honestly, think about any other only-gas powered car, when you try to accelerate faster, they do make the engine sound, it's just a matter of the type of the sound that may bother you because hybrid makes it more like a vacuum cleaner sound whereas the gas engine makes more powerful sound [img= class=inlineimg]/forum/images/smilies/smile.gif[/img]
