The MERCEDES-BENZ SLK (2004-08) 280 ROADSTER 3.0 231 is a compact, two-seat convertible in the premium sports-car corner of the UK used market. Its folding hard roof offers open-air driving and coupe-like security when closed. It is a stylish alternative to ordinary hatchbacks, rather than a practical family car. Mycarcheck.com has recorded 221 checks across 128 distinct VINs, a useful snapshot of interest in this model. Checked examples average 84,000 miles and four previous keepers, with around 3,000 miles driven annually; the average private-sale valuation is £3,400. These are observed figures, not a price guide, and condition and history can change a car’s worth considerably. Best suited to couples or solo drivers, it works for weekend outings and commuting, not family duties. Its six-cylinder performance and refined feel distinguish it from the lighter Mazda MX-5, though running costs exceed those of an everyday hatchback.
