Back around the year 2000 there was generally a lot less ornamentation and shapes were cleaner. There also was a minor fad for so-called Retro designs, where features of cars from decades earlier were hinted at.
A somewhat obscure concept car from that era is the Chevrolet SS, first shown at the Detroit auto show early in 2003. It displays some of the characteristics just noted. However, its design features didn't appear on future Chevrolet sedans.
