We say The SLK is attractive, offers a great handling and some good engines. It compares well to rivals, but it's a little more priceyPerformance 1.8, 3.0 and 5.5-litre engines are all eager. The first is adequate, the latter a monster and the middle one just right in terms of performance and running costs.Emissions Improvements in 2008 led to 182g/km of CO2 emissions from the 1.8-litre. Fuel economy is still average for a roadster.Driving A taut body means the Mercedes SLK does not suffer from the dreaded ‘skuttle shake’ experienced with some convertibles. More refined than its rivals but can’t match them in terms of handling.Feel The SLK is controlled even with the roof down and it is quiet with the roof up or down. The ride is fine, even on optional Sports suspension and it delivers a comfortable drive.Space The boot is a good size but with the roof down it is not particularly practical. There is comfortably enough space for two in the SLK.Equipment Standard equipment reads like an executive-level car; climate and cruise control, CD changer, alloys, satnav, leather... everything you could ask for.Price You don't expect economy or low tax from a car like this, but at entry-level it's good for the £30,000 price. Bigger engines will be costly in terms of running costs but residuals will be good.Quality The car is well built but there are a lot of complex electrical including that metal folding roof. In terms of materials and comfort in the cabin, it is as premium as you would expect from Mercedes.Safety Airbags and drivers aids helped this to a five-star crash rating. The traction system adds more grip and stability around corners.Pros The Mercedes SLK is sporty, looks fantastic and all three engines deliver performance and power. It is more refined than many rivals and feels taut and controlled on the road.Cons The cost is high and it is not cheap to run.Alternatives BMW Z4, Audi TT, Porsche Boxster, Mazda MX-5, Lotus Elise
