My dad has the 2007 V6 and my 4 cyl rides just as smooth if not better than his! The design in this car is brilliant all around, very comfortable seats, drive-by-wire makes steering so smooth you'll think you are controlling the car with your mind. Safety features are top notch. I was researching new cars for months, the '08 Accord always came out on top, once I test drove it I signed the papers right away. This car feels like an Acura with a Honda badge on it. Definitely looks and feels like a car worth more money than what you will pay for it.
Drive-by-wire, XM, iPod connection, dual climate control, very smooth and quiet ride, standards wheels are really nice.
Bluetooth on EX-L models without navigation, I can't think of anything I'd add to this car that it doesn't already excel in!
