Parkers overall rating: 4 out of 5 4.0

You don’t need to be an expert to identify the diesel, rather than the turbocharged petrols, as the winner here.

Low CO2 emissions and high (claimed) mpg figures suggest the 250d is the one to go for if you’re concerned about keeping costs down.

Pick the SLC 250d if you want low CO2 emissions – this produces just 114g/km despite being a sporty open top roadster.

Second- and third-generation cars have been largely problem free and we expect nothing different from this mildly updated version.

How much is it to insure?

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.
