Compared Volvo S60, Acura TL, Audi A6, Infiniti I35, Jag X-Type and Lexus ES. Selected the ES due to quiet cabin, smooth ride, comfortable seats, adequate acceleration, Lexus reliability. Dealer is extremely easy to deal with. This is my 4th Lexus - Have never had one in the shop for anything except scheduled maintenance.
Extremely quiet cabin. Excellent ride.
A little more oomph under the hood would just about make the ES perfect.
