2004 Mercedes-Benz SL 5.0L Petrol · AT02 AND

The most recent MOT on 20 July 2026 recorded a full pass with no recorded defects, indicating that the vehicle presently meets the statutory safety and emissions standards. Over the four‑year MOT window the car has shown a generally stable maintenance record, with only two advisories concerning rear tyre wear in 2022 and 2025 and no substantive failures. The absence of recurring mechanical faults suggests that the core systems – engine, transmission, brakes and suspension – have been kept in an acceptable condition, although the tyre advisories flag a modest trend that should be monitored. At 94 656 miles for a 2004 model the average annual mileage works out at roughly 4 300 mi per year, well below the typical 8‑10 000 mi benchmark for a vehicle of this age. Such low utilisation often points to periods of limited use or extended storage, which can be as consequential as high mileage. Light use reduces wear on consumables such as brake pads, clutch discs and tyre tread, but it also allows rubber to age, battery plates to sulphate and metal components to develop surface corrosion when the car sits for long intervals. Consequently, the mechanical wear profile is likely to be modest, but age‑related degradation may be present. Prospective buyers should give the rear tyres particular attention, as the MOT advisories highlighted tread approaching the legal limit and edge wear on both sides. Verify the current tread depth with a calibrated gauge, inspect the sidewalls for cracking, dry rot or bulging, and confirm that the tyres are of the same size, type and age. Uneven wear patterns could indicate mis‑aligned suspension, worn camber or toe settings, or failing rear bushings; during a test drive listen for clunking or knocking from the rear axle, especially over bumps, and feel for any pull to one side when steering. A visual check of the suspension bushes, coil springs and anti‑roll bar links for cracks, oil leakage or excessive play will help confirm that the low‑mileage usage has not allowed hidden deterioration. Given the vehicle’s age, a thorough inspection of time‑sensitive items is essential. Examine the 12‑volt battery for corrosion on the terminals and test its cranking voltage; a battery that has been idle for long periods may require replacement even if it still holds a charge. Inspect the brake discs for surface rust, scoring or glazing, and ensure the calipers move freely without sticking – a common issue on cars that sit unused. Check the condition of all fluid reservoirs – engine oil, coolant, brake fluid and power‑steering fluid – for colour, level and any signs of contamination, and consider a complete fluid change if the last service date is unclear. Finally, review the service book for evidence of regular oil changes, timing‑chain or belt service (depending on the specific SL engine), and confirm that any major scheduled maintenance such as suspension component replacement or exhaust system checks has been performed, as these are critical to preserving the car’s long‑term reliability.
