Running costs

4 out of 5 4.0

Mercedes-Benz maintenance is expensive, but it's essential if you want to keep its value. This will be repaid by strong residuals, even though it has just been replaced by a new and rather better model. Fuel economy isn't bad, especially on the smaller engined, supercharged models.

Vehicle excise duty (VED) varies according to the CO2 emissions and the fuel type of the vehicle. For cars registered before 01 March 2001 it is based on engine size. For cars registered on or after 01 March 2001 the VED or road tax is based on the car's CO2 emissions.

Green credentials

1.5 out of 5 1.5

SLK is a polluting model. With an average of 247 g/km CO2 across the range, its emissions are quite high for a sports roadster. It's worth noting that the line-up does not feature any diesel models, which typically produce less carbon dioxide than petrol engines with similar power outputs. The range is quite thirsty, averaging 27 mpg.

Highest and lowest CO2 emissions

Engine CO2 emissions Road tax (12 months)
230 Kompressor Petrol 220 g/km (Min) £265
320 Petrol 274 g/km (Max) £265 - £325


5 out of 5 5.0

It's a Mercedes-Benz – build quality is peerless and reliability almost unrivalled. Especially impressive when you see that wonderfully complex folding roof mechanism working.
