We did all kinds of tests with the other E70s and the results were the same. Sitting at the driveway entrance on route 1 and listening to the traffic go by. Him outside and me inside talking to each other with the windows up, first with the engine off and then with it running. Stereo on and how much you can hear it from outside with the windows closed. You get the idea. He agreed with me that the E53 was quieter and so are the other models. Off the record he thinks that the E70 is not insulated as well as the E53 was in an effort to keep the weight down. If you've ever opened the hood on an E53 and on an E70 you know what I mean.
