The 3.0-litre V6 unit plugs the gap between the entry-level SLK 200 Kompressor and the SLK 350. With 231bhp and 300Nm of torque, it propels the car from 0-60mph in only 6.2 seconds. And while the engine doesn't sound as meaty as rivals' - including Nissan's 350Z Roadster and BMW's Z4 3.0 - it's well mannered nevertheless.
Our car was fitted with the 7G-Tronic automatic transmission - an option at £1,770. This offers quick shifts, but has a tendency to hunt for the right ratio. Keen drivers will also be disappointed by the lack of precision from the brakes.
Still, the chassis is well balanced and the steering offers crisp turn-in. This is blended with a supple ride quality, which helps improve comfort on long trips.
Using the Vario roof is simple, and there's even a fairly practical boot. As with other models, the SLK 280 suffers some scuttle shake, but the latest Merc is still a great addition to the range.

I have to say the SLK 280 is a Fantastic car - apart from obvious the stunning looks, the engine is smooth as silk and whilst in comfort mode the 7G Tronic box is like velvet. Flick the switch to sport and the whole car is a pocket rocket. The free rev ving engine notes are much better enjoyed with the top down - quite frankly this is the best fun I have had in a long time - I love this car - my life is complete !!!
