Citroen GS Price Guide

The Citroën GS of 1970 brought hydropneumatic suspension to the family car class for the first time. It applied the DS and CX’s self-levelling technology to a smaller, more affordable car and produced something that rode and handled better than any car of its size and price. It won European Car of the Year in 1971.

The Car

The GS used a new 1,015cc flat-four engine (later 1,222cc) mounted transversely, with hydropneumatic suspension, inboard disc brakes, and the automatic height correction that gave the DS its legendary ride. The GS Birotor of 1973–1975 used a twin-rotor Wankel engine. This was an expensive, fuel-thirsty experiment that Citroën bought back from owners after the oil crisis. The GS estate and Club variants provided practical alternatives to the standard saloon.

Buying

The GS is one of the most undervalued Citroëns; an exceptional car that has not yet fully attracted collector attention. Hydraulic sphere condition and the flat-four engine’s cooling system are the priorities. Rust in the usual Citroën areas. The Citroën Car Club GS section and a good French car specialist are the resources. Avoid the Birotor unless you have a specialist who knows the Wankel.
