I have completed more than a thousand miles in the three Caterhams. The sounds of the 360 and 620 are delightful but the 270 leaves me feeling like something is missing. At slow peed there is a crackling noise that sounds like the engine is going to disintegrate into a thousand pieces and then, once one gets going the car sounds like a tame little pussycat. Listening to videos on youtube, I get the impression that the car has a much richer sound than what I am experiencing in Automobilista. Any thoughts on how to improve the sounds of the 270?
