At this writing (2010), the Lexus IS models.
Lexus does put a lot of effort into reducing the amount of road, wind, and engine noise that gets into the passenger compartment. So does Mercedes and Buick. If you check the automotive reviews of say, Car & Driver, their more thorough reviews include dB readings at idle and at 70 mph. A reading below 70 dB at interstate speeds will be pretty good. The very quietest cars will have readings in the mid 60's. Honda puts a lot of effort into producing quiet engines and little effort at reducing road noise. I doubt any of their compact cars would make your list. Fortunately, manufacturers have really made great strides in recent years at making their cars quieter and most advertise it when they do. GM's new compact sport utilities are said to be quiet and Buick touts all their cars to be very quiet. Road testing the cars that you are interested in will be the best way to decide. Find a concrete highway, turn off the radio, turn down the fan speed, and just listen. Once you have chosen a car, you can further improve the quietness when it comes time to replace the tires. Tirerack.com has excellent information and reviews of tires and one category they rate is the quietness of the tires.
