[2] The Indy was conceived as an alternative to the Ghibli offering a V8 engine and room for four people; it effectively replaced both the ageing six-cylinder 2+2 Maserati Sebring—which descended from the 1957 3500 GT— and the first generation Quattroporte.

On Ghia's stand there was the Simùn, a 2+2 berlinetta designed by Giorgetto Giugiaro; on Carrozzeria Vignale's, a sleek 4-seater fastback penned by the internal technical office led by Virginio Vairo[1] and Elio Mainardi.

[3] Both coachbuilders had already an established relationship with Maserati, as Vignale had been responsible for the 3500 GT Spyder, Mexico and Sebring, while Giugiaro had recently penned the Ghibli at Ghia.

From 1970 a 4.7-litre Indy 4700 was offered alongside the 4200; the same year some interior updates were introduced, including seats with retractable headrests and a new dashboard.

At the rear there was a live axle with semi-elliptic springs, a single longitudinal torque arm, hydraulic dampers and an anti-roll bar.
