I find the road noise quite low. And I think its the only noise left as the car is so quite. Road noise is certainly much lower than the late model commodore I had previously. The Hancook tires that are fitted to the M3 LR may not be the best for noise but it does not worry me presently.Oh Henny congratulations! I think easily the best Christmas present ever! I still find the road noise is a bit too much... Probably because is good performance sticky tyres... Hoped it wear out quickly and I will change to Pirelli dragon sport or P zeros.
