MERCEDEZ-BENZ is set to launch an exclusive special edition of its sporty SLK-Class Roadster.

Only 250 units will be available with a choice of three engines: two-litre supercharged, 2.3 litre supercharged and 3.2 litre V6 with either a six-speed manual gearbox or five-speed automatic transmission.

The SLK Special Edition adds to the standard cars' generous specification with 7.5J x 17 Evolution alloy wheels; black nappa leather upholstery with silver accents; brushed aluminium interior trim and silver instruments with white dials and highlighted surrounds.

Available from next month, the SLK Special Edition costs from £25,890 for the SLK 200 KOMPRESSOR. The SLK 230 KOMPRESSOR is £29,090 and the range-topping SLK 320 costs £32,040, all of which are on the road prices.

The Special Edition's features add some £600-worth of extra value compared with normal equivalent option list prices.

Dermot Kelly, Director Mercedes-Benz Passenger Cars and smart said: "The SLK-Class Roadster is one of the most stylish open sports cars on the road, and its popularity keeps on growing.

"Our new Special Edition improves on what is already a stunning roadster with stylish appointments that give a hint of its remarkable new SL-Class stablemate."

All SLK-Class Roadsters have the engineering and performance to back up their looks.

An electro-hydraulic folding metal vario-roof changes the car from coup to topless in just 25 seconds.

Four airbags, ESP Electronic Stability Program, ABS anti-lock brakes with Brake Assist and doors that lock automatically above 5 mph add to the safety and security tally.

Every new Mercedes-Benz passenger car bought in the UK from an authorised retailer has a three-year unlimited mileage warranty and ASSYST variable service intervals as standard.

The SLK-Class Roadster also includes Mercedes' industry-leading 30-year mobilo-life cover, which provides anti-corrosion and breakdown cover for three decades.

The new SLK Special Edition adds even more exclusivity and desirability to a potent mix of great looks, sporting credentials and the versatility of both hard and open top motoring.
