the sound's at higher revs are different for each car,but both are great.

hands down the 370 has a smoother ride. i think most of the road noise comes from the crappy bridgestone tires.

i have no rattles or other issues (knock on wood)

anyway anyone who has owned both will tell you the 370 is twice the car the 350 is except for the 350 drivers.
