From the 1960's this car comes with working headlights (AG 1) and opening doors (AG 2+VTOL/Trim). Not really too much to say, so here is what Wikipedia has to say on it:

For the 1968 model year, GM instituted a split-wheelbase policy for its A-platform intermediate-sized cars. Two-door models would have a 112 in (2,845 mm) wheelbase, 116 in (2,946 mm) for sedans, and 121 in (3,073 mm) for station wagons. In 1969, GM introduced the Pontiac Grand Prix, a two-door that used A-platform layout that was stretched ahead of the firewall to make it 210.2-inch (5,339 mm) long. This gave the design an unusually long hood design helping the new Grand Prix to outsell its larger B-body predecessor, despite higher prices. The new layout was first known as the A-body Special, but would evolve into its own class known as the G-platform.

The Monte Carlo started as a Chevrolet counterpart to the Pontiac Grand Prix, as conceived by Elliot M. (Pete) Estes, general manager of Chevrolet, and Chevrolet's chief stylist, David Holls. They modeled the styling on the contemporary Cadillac Eldorado, although much of the body and structure were shared with the Chevrolet Chevelle (firewall, windshield, decklid, and rear window were the same). New exterior "coke bottle styling" featured concealed windshield wipers. A light monitoring system was optional.[3]
