With its eye on the MGB GT, Nissan unveiled its Fairlady Z fastback coupe in the late 1960s. The car’s striking long hood and short tail proportions proved just right for magazine covers and bedroom posters, but enthusiasts appreciated its balanced handling and torquey inline six-cylinder engine.

The Z proved especially popular in the U.S., where it was marketed as the Datsun 240Z. However, the American market missed out on the Group 4 homologation special introduced in 1971—the Japan-only Fairlady 240ZG. The “G” in its name stood for “Grand,” which fits its larger-than-life styling. The 240ZG enjoys legendary status in Japan thanks to its 1972 Fuji Grand Champion Series win.

The differences between the Z and ZG are immediate at first glance. The squat fiberglass nose with acrylic headlight covers cheat the wind and give the coupe its own styling personality and channels stylist Yoshihiko Matsuo’s early designs. The over-fenders riveted to its body begged for wider wheels, just like the Group 4 cars. A mere three colors were offered, the most striking of which was the Grand Prix Maroon of the 240ZG offered here.

This authentic example—a factory-original Fairlady 240ZG—is well known among Japanese car collectors. It was delivered new in the Shinagawa ward of Tokyo. More recently, it was treated to a thorough refurbishment that included a new paint job in its original shade. Its signature over-fenders remain striking. Inside, the 240ZG retains its original black vinyl upholstery. A Datsun racing steering wheel provides a good view of its hooded gauges. A period Nissan AM radio takes up residence low on its dashboard.

Underhood, the 2.4-liter inline six shows some evidence of use but has been thoroughly detailed. New, original-specification shock absorbers are said to provide a comfortable yet sporty ride. The original wheels have been swapped for period-style Watanabe wheels and a rear strut brace is its only other visual modification.

This 240ZG is one of a mere handful—if even that many—in the U.S.
