It depends on the road. It's fine on a smooth road. I drove from mid-New Jersey to Long Island when I bought mine and the ride quality was not
at all an issue. However when I visited my cousin on Staten Island
a month later, I got a feel for the neglected pot-holed roads there
and my wife started complaining about the ride.
As long as the roads are fairly well maintained, The firm ride
of the Srt is fine, although you will feel any imperfection or
tar strip.
