Our Verdict
Proceed with caution. While the mileage
Your primary focus should be the February 2024 MOT failure. Specifically, you must confirm that the Supplementary Restraint System (SRS) warning lamp fault has been professionally repaired, as this affects airbags and seatbelts. Additionally, verify that the offside front service brake binding issue was fully rectified and not just a temporary fix, as this can lead to premature wear of the braking system.
Given the low mileage recorded between 2021 and 2023 (approximately 2,272 miles), this vehicle may have spent significant periods stationary. Check the service history for evidence of regular oil changes regardless of mileage, and inspect the tyres for flat spots or perishing due to inactivity.
The 1.8L petrol engine offers a balance of performance and economy, though it will be more expensive to run than a modern small-capacity engine. Expect moderate fuel costs and a tax band consistent with 2007 emissions standards. Insurance groups for the SLK are typically higher than standard coupes due to the vehicle's classification.
Maintenance costs for this model can be higher than average, particularly regarding the complex folding roof mechanism and specialised Mercedes-Benz parts. Budget for annual servicing and the potential for electrical component replacements as the vehicle ages. The estimated annual running cost is approximately £1,200-£1,600.
Start by checking the dashboard for any active warning lights, specifically the SRS lamp mentioned in the 2024 MOT. Test the horn and all external lighting, including the dipped beams, to ensure the 2023 and 2024 electrical failures have been permanently resolved.
Perform a thorough inspection of the braking system. The 2023 record noted pitted and scored front discs, and the 2024 record noted a binding brake; check for uneven disc wear or overheating signs. Finally, operate the roof mechanism multiple times to ensure smooth movement, as this is a known high-cost area for this model.
This silver 2007 Mercedes SLK with a 1.8L petrol engine has recorded relatively low mileage, sitting at 90,829 miles as of January 2023. The MOT history is mixed, featuring a clean pass in 2021 followed by failures in 2023 and 2024. The most recent test in February 2024 highlighted concerns regarding the braking system and the supplementary restraint system (SRS).
Aggregate data for this model is unavailable, but this specific vehicle's history shows a trend of braking and electrical faults in recent years.
