So I have a buddy who reviews cars for a living and he gets a different car every week to review/test, he has been doing this for about 7 years now...
...and out of the approx. 360 cars he has reviewed to date this is hands down the best sounding one ever (and that list includes R8's, 911's, GT500's, M3's, RS4's, basically if its not an Italian and you can think of it, he has had it).
