We have a M B SLK 200, 2003 6 speed manual, 59,000 kilometers.Recently wehave beengetting an intermediate clutch problem. The clutch can be fine and then we lose pressure on the first half of the pedal travel. Once the pedal is to the floor the gearbox changes normally.When the pedal is released it sticks half way and you have to put your toe under it to pull it up fully. Have spoken to M B and they are saying to change the flluid, master cylinder and slave cylinder. Any clues?
