had small moveable vents. With the rear window regulators no longer required, Chevrolet was able to recess the door arm rests into the door cavity, resulting in a few extra inches of rear seat room. Customers complained about the lack of rear seat ventilation. No doubt this design contributed to the number of factory air conditioning units sold with the cars, to the benefit of General Motors and Chevrolet dealers. For the 1981 model year, sedans adopted a four-window profile and "formal" pillared upright roofline. The two-door coupe was last produced in this year, as the Monte Carlo assumed the market position held by the 2-door coupe. For 1982 the Malibu was facelifted with more squared-off front styling marked by quad headlights with long, thin turn signals beneath them. The look was very reminiscent of the also recently facelifted Chevrolet Caprice. For 1983, Malibus gained a block-style "Malibu" badge on the front fenders to replace the cursive-style script located on the rear quarter panels of previous model years. The four-door Malibu was commonly used in fleet service, especially for law enforcement. After the Chevrolet Nova ceased production in 1979, the mid-sized 9C1 police version (not to be confused with the full-size Chevrolet Impala 9C1 which was also available) was transferred to the Malibu, filling a void for the mid-sized police patrol cars. A 9C1-equipped Malibu with an LT-1 Z-28 Camaro engine driven by E. Pierce Marshall placed 13th of 47 in the 1979 Cannonball Baker Sea-To-Shining-Sea Memorial Trophy Dash, better known as the Cannonball Run. There was no factory Malibu SS option available on this generation. The SS only came in the El Camino. The rare, and striking, 1980 Malibu M80 was a dealer package for only North and South Carolina. It was mostly aimed at NASCAR fans who regularly traveled to Darlington Raceway. To this day, the number actually produced is unknown; estimates place this around 1,901 cars. All M80s had to be white with dark blue bucket seats and center console interior. The base of the M80 was a two-door sport coupe equipped with the F41 Sport Suspension package and the normal V8 (140 hp) drive train. The M80 option added two dark blue skunk stripes on top and a lower door stripe with the M80 identification. The package also added front and rear spoilers and 1981 steel rally wheels (sourced from the 1980 Monte Carlo). In Mexico,
