Purchased this car from previous owner, a family member, because it had been beautifully and carefully maintained. BUT....

It is the noisiest car I have ever been in...not because of the engine but because of road noise. It is virtually impossible to hear the radio unless it is blaring or to converse with a passenger without shouting. Even putting on expensive brand new tires didn't help! It is as if there was no floorboard between the interior and the road! Help!
