The people's car that became a classic icon
The 2CV has transcended its humble origins to become a lifestyle icon and accessible entry point into classic car ownership in the UK. Values have risen steadily — good examples now fetch £5,000-£8,000 with excellent cars reaching £13,000-£14,000. A mature, liquid market with strong specialist support and comparatively affordable running costs makes it one of the most approachable classics to own.
We track 5 known issues across the Citroen 2CV range, including 2 rated as safety-critical. Knowing which variants and configurations to approach with caution can save you from expensive surprises after purchase.

2CV_CLASSIC (1958–1990) — Engine options included the 602cc flat-twin. Our database flags 5 known issues on this generation, 2 of which are rated as safety-critical. The most significant concern is Stub axle to beam movement excessive (£300–£600 to address).
The stub axle mounting to the trailing arm assembly develops excessive movement at 412.6 times the fleet average rate, particularly on higher mileage cars. The 2CV uses a unique trailing arm suspension with the stub axle bolted directly to the arm end. Wear in the stub axle bearing, arm bushes, or mounting bolts creates dangerous wheel movement that can cause sudden loss of control. This is a fundamental weakness of the 2CV suspension design under modern road conditions.
Excessive stub axle movement can cause sudden wheel detachment or complete loss of directional control, particularly under braking or cornering. The car should not be driven until repaired. Repair typically requires stub axle replacement, trailing arm bush renewal, and possibly trailing arm replacement if mounting points are worn.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Structural corrosion affecting assembly rigidity occurs at 44.5 times the fleet average rate. The 2CV's steel monocoque construction with minimal rustproofing is highly susceptible to corrosion, particularly around the A-pillars, door frames, rear suspension mounting points, and floor pan. The thin steel used in construction corrodes quickly when the factory protection fails. Many survivors have had previous welding repairs that may not meet modern structural standards.
Structural corrosion severely compromises crash protection and can lead to MOT failure on safety grounds. Extensive welding repairs can cost £2,000-5,000 depending on extent of corrosion. Many examples are beyond economic repair when structural corrosion is advanced. The car should not be driven if structural integrity is compromised.
Inspect the wheel arches, sills, jacking points and door bottoms carefully. Press gently on sills to check for soft spots. Look underneath for corrosion on structural components. Check the MOT history for corrosion-related advisories or failures.
The 602cc flat-twin engine fails emissions testing at 434.5 times the fleet average rate, the highest failure rate in the MOT statistical data. This is primarily due to the primitive carburetor system, lack of catalytic converter, and age-related wear of the combustion chambers. The air-cooled engine design runs inconsistent combustion temperatures, and worn valve guides allow oil burning. Modern emissions standards were not considered when this engine was designed in the 1940s.
MOT failure requires immediate rectification before the car can be driven legally. Carburetor rebuild, valve guide replacement, or engine overhaul may be needed depending on root cause. Costs range from £200 for carburetor service to £2,000+ for engine rebuild. The car remains driveable but cannot pass MOT without repair.
Check for any engine warning lights on the dashboard. Ask about the car's MOT emissions history — repeated failures suggest underlying issues. A pre-purchase diagnostic scan is especially worthwhile to check for stored emissions fault codes.
Suspension pins, bushes, and joints wear at 140.3 times the fleet average rate across all mileage ranges. The 2CV's interconnected suspension system uses numerous rubber bushes, metal pins, and ball joints that were designed for 1940s road conditions and vehicle weights. The trailing arm system places high loads on bushes, and the soft suspension allows significant movement that accelerates wear. Age-related rubber deterioration affects even low-mileage examples.
Worn suspension components affect handling, tire wear, and MOT compliance. Multiple components typically need replacement simultaneously due to system interconnection. Complete suspension refresh can cost £800-1,500 depending on extent of wear. The car remains driveable but handling deteriorates progressively.
Listen for knocking, clunking or rattling over bumps during the test drive. Inspect the underside for corroded or cracked suspension components. Check the MOT history for suspension-related advisories, which often predict future failures.
Wheel bearings fail at 61.3 times the fleet average rate for roughness and 24 times for excessive play. The 2CV uses simple roller bearings in the stub axle assemblies that are exposed to contamination through aging seals. The lightweight construction and age of these vehicles means bearing seals have typically hardened and lost effectiveness. Road salt, water ingress, and lack of regular maintenance on vehicles often stored outdoors accelerates bearing deterioration.
Severely worn bearings can seize or collapse, causing wheel lockup or detachment. Bearing failure while driving can cause loss of control and accident. Early-stage bearing roughness affects braking efficiency and tire wear. Bearing replacement typically costs £150-300 per wheel including seals and adjustment.

Based on 17k real DVSA MOT tests, the Citroen 2CV fails more often than average on several items. The biggest outlier is axle or kingpin wear at 6513x the fleet average, followed by emissions failure (435x).
When viewing a specific car, check its MOT history for recurring advisories in these categories. See the full Citroen 2CV MOT failure breakdown for data at every mileage point.
Routine servicing (oil and filter change every 3k miles) typically costs £40–£60 at an independent garage.

The Citroen 2CV has some well-documented weak points, including 2 safety-critical issues that demand careful checking. The right example, properly maintained, can still be a sound purchase — but cutting corners on the pre-purchase inspection is not advisable. The 2CV6 (1970 onwards) with its 602cc engine and 12-volt electrics is the most practical choice for regular use. Later cars from the 1980s benefit from incremental improvements. The rare Sahara 4x4 twin-engine variant commands up to £90,000 but is essentially a collector piece.
