2012 Mercedes-Benz SLK 1.8L Petrol · P1 JJL

The 2012 Mercedes-Benz SLK presents a stable and improving maintenance trend, culminating in a fully clean MOT pass on 22 January 2026 at 102,272 miles with zero advisories or defects. That clean bill of health is a strong indicator. The previous three tests, however, tell a more nuanced story of minor but recurring wear items being managed rather than ignored. The most recent test confirms that any lingering issues flagged in prior years have been rectified, and the vehicle is currently in sound mechanical order. The mileage accumulation is consistent and unremarkable for a 14-year-old car, averaging roughly 7,305 miles per year. Between the January 2023 test at 85,579 miles and the January 2024 test at 91,144 miles, the car covered 5,565 miles in twelve months. The following year it added 5,448 miles, reaching 96,592 miles by January 2025. The most recent interval saw 5,680 miles added over the past year. There are no suspicious gaps or sudden spikes in the odometer record, suggesting regular and sustained use rather than prolonged standing, which can cause its own problems with seized brakes and perished rubber components. The recurring theme across the MOT history is front brake disc wear. Both front discs were flagged as worn in the January 2024 test, and the January 2025 test again noted a worn front disc, though not excessively so. This pattern is entirely consistent with a car driven in mixed conditions where front brakes naturally bear the greater braking load. The fact that no brake defects appear in the January 2026 test indicates the discs and pads have been replaced and are now within specification. A buyer should still inspect the current condition of the front brake discs, pads, and rear braking components in person, checking for uneven wear, lipping, and pad thickness. Beyond the braking system, the January 2025 test flagged slight play in the offside front wheel bearing, a defect that does not appear in the subsequent 2026 test, suggesting it was addressed. Prospective buyers should still listen for any whining or rumbling from that corner during a test drive and check for play by rocking the wheel at the twelve and six o'clock positions. The failed test on 12 January 2023 for a deep cut in the offside rear tyre reaching the cords is a one-off event with no recurrence, but it does indicate that basic tyre condition checks were not always carried out promptly. Inspect all four sidewalls carefully for cuts, bulges, and uneven wear, and verify that the spare tyre, if present, has not been neglected.
