Is the Mercedes-Benz Clk ULEZ Compliant?
Based on 32,401 MOT tests, around 28% of Mercedes-Benz Clks still on the road are likely to meet London's ULEZ standards, and about 28% are likely to be charged. For the remaining 43%, it depends on the exact Euro standard or month of registration.
The fuel mix matters: tested cars were 80% petrol, 20% diesel. Petrol Clks are generally compliant from 2006, while petrol cars from 2000 or earlier are likely to be charged. Diesel Clks in the data are mostly from years that are unlikely to comply.

How ULEZ rules apply to the Clk
Cars that miss the standard pay £12.50 for each day they're driven in the zone. Petrol and petrol-hybrid cars need Euro 4 (most from 2006), while diesels need Euro 6 (most from September 2015).
- Petrol (80% of Clks tested): likely compliant from 2006; 2000 and earlier are likely to be charged.
- Diesel (20% of Clks tested): most cars in our data are from years unlikely to comply.

Buying a used Mercedes-Benz Clk for London: what the MOT data shows
The Mercedes-Benz Clks in this data were first registered between 1998 and 2010. 2004 was the most common year, with 4,534 tests (14% of the total), and half were registered in 2005 or later.
Clks from likely-compliant years passed their MOT first time 61% of the time, at an average of 101,472 miles. Older ones likely to be charged passed 63% of the time with 102,970 miles on average.
On a budget, the oldest petrol Clks likely to comply are from 2006. 2,579 of them were tested; 2006 cars passed first time 61% of the time and averaged 105,525 miles. Check the Euro standard on the V5C before you buy one from around then.
Whichever year you choose, check the Clk's weak spots. The most common MOT failures were suspension: "ball joint excessively worn" (7.8% of tests) and "fractured or broken" (7.1%); lights and electrics: "not working" (5.5%). The most frequent advisory was "excessively corroded", on 19.4% of tests.
Overall, 62% of Clks passed first time, well below the 71% average for all cars, and they had covered 103,679 miles on average, more than the 73,145-mile average.
