This is my second ES. The prior was an ES 330. The car is quiet in terms of road noise. Performance is great unless you are used to driving a high performance BMW. I';s easy to look down and see you are cruising at 80 thinking you are driving at 60. Interior materials are all high quality. I only have 2 complaints. First the sound system is sub-par for this class of vehicle. Second there is as persistant rattle in the sun-roof area that the dealer cannot seem to fix. There are also other bump related rattles that seem to develop during the first 20k miles.
Cooled seats. Nice combination of handling and ride. Great gas mileage. Quality interior materials. Comfortable car to drive.
