That's a rhetorical question. Yes they bloody have. At the moment which is your favorite engine sound? At the moment i'm torn between the Takata NSX, Integra Type R (I'm sure I can hear the V-Tec engaging) and the SL55 AMG. I've also noticed when you get to about 245kmph with the Takata NSX, the screen and tachs begin to shake about. I mean how cool is that?
