2005 Smart City Cabriolet 0.7L Petrol · CE05 NZW

The 2005 Smart City Cabriolet holds a valid MOT passed on 5 June 2026 at 86,520 miles, but the maintenance trend is clearly worsening. That pass came immediately after a failure on the same day at 86,518 miles, where the tester found an inoperative hazard warning switch, a parking brake inoperative on the offside rear, and parking brake efficiency below requirements. A retest two miles later resolved those items, yet the pass still carried four advisories. Both front coil springs are corroded on both sides, all four shock absorber casings are corroded, undertrays were fitted obscuring some underside components, and the rear subframe is corroded though not seriously weakened. The offside rear parking brake only just met efficiency, indicating the braking system requires adjustment or repair. This pattern suggests corrosion and brake issues are accumulating rather than being properly addressed. The mileage pattern tells a story of extremely light use with possible long periods of standing. The vehicle has covered roughly 4,120 miles per year over 21 years. Between the October 2022 pass at 85,607 miles and the July 2024 failure at 86,514 miles, just 907 miles were added over nearly two years. The 2026 tests then show the odometer climbing from 86,514 to 86,520 in a matter of days, which is consistent with a pre-sale check rather than genuine road use. Such low annual mileage can mean reduced consumable wear, but prolonged sitting accelerates corrosion of brake components, seals, and structural underbody parts, which is exactly what the record shows. A buyer should inspect the underside in person with particular attention to the front coil springs, where corrosion on both sides was flagged in the most recent test. Corroded coil springs are at risk of fracture, especially on a small city car that encounters urban road surfaces. The rear subframe corrosion advisory, while not deemed serious, warrants close examination given the vehicle's age and the tendency for corrosion to worsen once it takes hold. All four shock absorber casings are corroded, meaning replacement is likely imminent regardless of whether damping performance has degraded yet. The braking system demands a thorough check. The offside rear parking brake was inoperative during the June 2026 failure and only barely met efficiency on retest. This points to binding calipers, seized cables, or uneven adjustment rather than simple pad wear. A buyer should test the handbrake on a slope and check for dragging rear brakes during a road test. The undertrays fitted at the time of the latest test obscure some underside components, so removal is essential before purchase to properly assess subframe, suspension mounting points, and floor pan condition. The intermittent lamp and switch faults from 2024 appear resolved, but electrical gremlins on older Smart vehicles are common and should be verified.
