love the diff between my '11 and my '07. but the ride is still rough. can i use Goodyr. Comfort Rides on it..or something similar? or..what is best..for quiet..comfy ride opp??
Have you checked your tire pressure? Cars usually leave the factory with the tires overinflated (so they don't go too low during transit), and it could be the dealer didn't adjust them during the PDI. Your profile doesn't show which model you have, but on my Prius V (w/ 17" wheels), as little as 5 PSI over the recommended pressure can result in noticeably rougher ride.
