Yes the roads here in Finland has alot of rough tarmac, and the car is more quiet on better tarmac.
I will see if I go and testdrive a Civic at a car dealer to see if there is any difference in road noise.
I just wish I would have the money to buy a Lexus. I test drive a RX300 a few years ago and it was so quiet

But then the price difference is another too compared to the Civic
