I used to own a 2010 ES 350 with special tires for a smooth ride. I remember I would frequently go past 100mph and it was like driving on clouds.
My favorite car from a looks standpoint is an Audi S5, but I test drove that vehicle and it was a much rougher ride at high speeds. Didnt strike me as a luxury car.
If I wanted the ES 350 ride in a more sporty looking body, what car would that be?
