the 05 RX330 has done 1000 miles so far, and it is starting to be not as sound resistant as before. when i first drove the car, it was so quiet you couldnt hear the Mac trucks pass by, but now it's very noticable to hear the sounds of other car's exhaust notes and the 'whoosh'. the road noise also seems to be very noticable and the engine causes the cockpit to vibrate more than when it was driven at 300 miles - you couldn't even feel the engine running. finally, the ride is bumpy as hell even on smooth surfaces. does anyone know about fixes or have experienced these problems with their car?
