I have only had this car a week, but oh what fun! The run flats I think do give this car a ride a bit more impulsive over bumps, but the highway ride is still very quiet and smooth. I bought mine "used" 2K miles but it was essentially new. The tags were on the upholstery. This car does make people do 'Linda Blairs'. The colors and styling are a knock out. Mine is amethyst with the ecru interior and birdseye maple. People just love it.
Navigation system, memory seats, mirrors and steering, the sound system, the retract roof, the exterior sytling, the power. The interior just makes you feel like you're in a private jet or yachet with the oppulance of highly polished wood and leather everywhere.
