The MERCEDES-BENZ SLK (2004-08) 200K ROADSTER 1.8 163 AUTO is a compact two-seat convertible, aimed at drivers wanting premium style and open-air motoring rather than family practicality. In the UK used-car market, it sits among affordable prestige roadsters, offering a more exclusive feel than hatchbacks. Mycarcheck.com has recorded 3,134 look-ups covering 1,287 different VINs, a substantial sample; checks began in February 2021. Its average private-sale value is £2,700, with typical recorded mileage of 86,000 miles and annual use of around 3,000 miles. The average keeper count is about five, suggesting many have changed hands over time. The 200K’s supercharged petrol engine and automatic gearbox make relaxed cruising easy, while its folding hardtop gives coupe-like security and a sunny-day convertible feel. It suits couples or solo drivers seeking weekend trips and commuting, not regular rear-seat passengers. Compared with Mazda MX-5 rivals, the SLK is more luxurious and refined, though upkeep deserves checks.
