Insurance rating class (Germany)Dated, data up to and including 2024

Applies to all generations of this model

Always correct for age. A group of younger cars is not automatically more reliable

  • GDV rating class: SLK

    According to the GDV rating-class register (rate year 2024), SLK has KH 10-14 (scale 10-25), VK 11-32 (scale 10-34), TK 14-22 (scale 10-33). Note: this range comes from 40 known engine variants in this rate year. GDV only looks at make and model here, not at the generation. With a count this high, several model generations may be pooled together. Note: this is an index figure or rating class, an insurance statistic about the whole model. It is not a chance of defects and not a prediction for this car.

Czechia only counts serious defects, severity B or C. The Netherlands, the United Kingdom, Ireland and Norway count every inspection with a real defect.

Finland is not in this table. Finland counts defect points, not cars with a defect.

100 is that country's average for that age.

All generations
