Sub-frame corroded on the Mercedes-Benz Clk
Sub-frame corroded on the Mercedes-Benz Clk is recorded on 6,130 tests — 5.9% of all its MOT tests, against 2.4% across every car in the data. That is 2.5× the national share.
Is this unusual for this model?
| Compared with | What it says |
|---|---|
| Every car in the data | 2.4% of tests record it — this model is 2.5× that share |
| The 291 models compared | 41 of 291, highest first |
| The model's own record | 104,027 tests · every year of the Clk → |
A share of tests is not a probability for your car: it counts every Mercedes-Benz Clk tested, whatever its mileage, service history and use. The like-for-like comparison on the model page is the fairer number.

Years with fewer than 0.2% of tests recording the item are left out: a year with two failures in 400 tests is noise, and this table is not here to make noise look like a trend.
