According to GM historian Dave Newell, Chevrolet had planned on ending Corvair production after the 1966 model year. Development and engineering changes were halted in 1966 on the year-old, redesigned second-generation cars with mainly federally mandated emissions and safety changes made thereafter. An increasing lack of interest from the company, especially from Chevrolet's General Manager John DeLorean, and a complete absence of Corvair advertising after 1967 reflected the company's priorities, including promotion of three redesigned models for 1968—the Corvette, Chevelle, and Chevy II Nova. The Corvair was referred to as "the phantom" by "Car Life" magazine in their 1968 Monza road test, and by 1969 Chevrolet's Corvair four-page brochure was "by request only". During its final year of production, 6,000 cars were produced.
