Steve Sutcliffe does an engine noise comparison on the UK autocar site - both sound great. 119db for the spider in the tunnel! We have a 5km tunnel in Dublin and I have been there with my cali and italia, a fantastic few minutes. http://www.autocar.co.uk/car-video/ferrari-vs-jaguar-which-sounds-best
Nice video. Look at that ear to ear grin he had driving that ferrari...I imagine that is exactly what it feels like to drive it every time.
