What most often fails on a Mercedes-Benz SLK at its MOT
Across 54,149 Mercedes-Benz SLK MOT tests in 2025 (all versions together), these defects turned up most often.
- Coil spring: fractured or broken. On 5.0% of Mercedes-Benz SLK tests, 1.5 times the rate for cars of the same age.
- Ball joint excessively worn. On 2.9% of Mercedes-Benz SLK tests, 1.3 times the rate for cars of the same age.
- Tyre tread below the 1.6mm legal minimum. On 2.0% of Mercedes-Benz SLK tests.
The MOT checks safety and emissions items, not the engine, clutch or gearbox, so this is one measure of how each car holds up rather than a full reliability verdict. These figures describe the model, all its versions together, not this particular car.
From DVSA’s 2025 MOT results. See the full analysis
What this car costs to run
Modelled over 7,100 miles a year (DfT National Travel Survey, England). Ranges, not quotes — every figure here is an estimate.
- Vehicle tax (VED)Registered 2012, so road tax depends on this car's official CO2 figure, which is not on the advert: £20 a year at 100 g/km or under, rising to £790 over 255 g/km. The CO2 figure is on the V5C: ask the dealer for it, or for the registration to check on GOV.UK. The rates by CO2 are in GOV.UK's vehicle tax band table

- £1,600–£2,200
- Insurance (UK average)The UK average premium actually paid for comprehensive cover, £566 in Q2 2026 (ABI) — an average across every driver, postcode and car, not a quote for this one.

A 17–20-year-old new driver typically pays more than this average: see our guide to the cheapest cars to insure as a new driver, or the ABI figures

- ServicingFrom a minor service (£300–£500) to a major one (£600–£1,100) on a Mercedes, from Autoza's own servicing estimates by make, not survey data. Routine servicing only — excludes repairs and tyres
- £300–£1,100
