About the Citroen CX2400
Launched in 1974 as the successor to the legendary DS, the Citroen CX won European Car of the Year and remained in production until 1991. The 2400 variant featured a 2.5-litre petrol engine producing around 115-128bhp depending on the year and specification. The CX's party piece was its self-levelling hydropneumatic suspension, which provided an exceptional ride quality unmatched by contemporary rivals.
Two main series exist: Series 1 (1974-1985) with single headlights and chrome bumpers, and Series 2 (1985-1991) with revised styling including rectangular headlights and plastic bumpers. Both offered saloon and estate (Break) body styles. The CX2400 was positioned as the mid-range petrol option, sitting below the GTi Turbo and diesel variants. Build quality varied, with later examples generally better assembled than early cars.
What Affects the Price
Condition is paramount with the CX2400, as restoration costs can quickly exceed the car's value. Rust is the primary concern, particularly in the rear suspension mounts, floor pans, and front chassis legs. Cars with documented suspension overhauls command premiums, as rebuilding the hydropneumatic system is expensive and specialist work is essential.
Original, unmolested examples are increasingly rare and valuable. Series 1 cars in good condition attract collectors, whilst Series 2 models offer more modern conveniences and improved build quality. Mileage matters less than service history and evidence of proper maintenance. Estate versions typically fetch slightly more than saloons due to their practicality and relative scarcity. Colour and specification also play a role, with desirable shades and period options like air conditioning adding value.
Buying Tips
Inspect the suspension thoroughly before purchase. The car should sit level when running, and the self-levelling system should respond within 15-20 seconds of starting. Listen for pump noise and check for fluid leaks around spheres and accumulators. A test drive should reveal the famous magic carpet ride; any harshness suggests worn components.
Check all electrical systems, as the CX features complex wiring that can be troublesome. Test the lights, gauges, and any optional extras. Engine-wise, the 2.5-litre unit is robust but check for oil leaks from the rear crankshaft seal. Manual gearboxes are more reliable than automatics. Join a specialist owners' club before buying, as they offer invaluable advice and can recommend reputable specialists. Budget for ongoing maintenance, as parts availability varies and some components require specialist knowledge to fit correctly.
