Which used Mercedes CLK coupe should I buy?
The four-cylinder engines become coarse at high revs, and even the V6 can sound strained when you work it hard. However, they're all quiet when cruising, and the CLK cuts out wind and road noise well.
Overall, the V6 offers the best blend of performance and running costs, and acceleration is effortless with it or the 4.3 V8 - and simply incredible with the 5.6 AMG. The only slowcoach is the non-supercharged 2.0-litre unit, but both the Kompressor engines are reasonably brisk.
