Automotive Collectible Category (year 2000 run) : New Millennium 'Sunfire GT/SE Convertible' also known as "Y2K" period runs, which includes all 1999 thu. 2001 Sunfire SE/GT Convertibles.
Class A Y2K PS SE/GT Conv.: A modified PS-SE/GT Y2K - Has nose upgrade (i.e. 95-99 SE/GT front bumper cover, GM or aftermarket) which is considered the better nose/cover design by many design professionals in keeping with good design practice and the 95-99 SE and/or GT longest running body style history. (2000 nose cover must be retained off-car in storage for industrial design context)
Class B Y2K PS SE/GT Conv: Has no 95-99 nose/front bumper cover upgrade applied to car and retains the 2000 front bumper cover on the car which is a cover considered by many design professionals to be an automotive design error after released for production by GM in 2000.
