The MERCEDES-BENZ CLK (1997-03) CLK230K 2DR COUPE 2.3 AVANTGARDE 6SP is a premium two-door coupe from the late 1990s and early 2000s, sitting between everyday family cars and pricier grand tourers in the UK used market. Its supercharged 2.3-litre petrol engine and six-speed manual give it a more engaging feel than a conventional saloon, while Avantgarde trim adds a sportier look. With rear seats and a separate boot, it can handle occasional passengers, though access and space suit couples or solo drivers better than families. mycarcheck.com has recorded just eight look-ups across seven distinct VINs, so its figures offer a small snapshot rather than a market-wide picture. Within that sample, the average private-sale valuation is £900, average recorded mileage is 119,000 miles, and annual mileage averages 3,000. Cars have averaged 4.5 previous keepers, making a careful history check especially worthwhile. Compared with the BMW 3 Series Coupe, the CLK is a comfort-focused alternative, with Mercedes prestige and elegant frameless side windows styling.
