97-02 Look better imo and are available in a coupe. 04 and up 4 door sedans only but the Gen V is appealing on the L32's. The GTX 8 cylinder is pretty cool also. 03's are the same generation as 97-02 but only available in 4 doors which personally I don't care for as much. I'd rather drive a Regal GS or an Impala SS if going with 4 doors.
