Strange hiccup on Mercedes 320 SLK clutch.
Bought used. 35K miles. Manual transmission. Have driven car for one week. Great response. This evening, pressed in clutch to engage 1st gear at take off from stop light. Heard a clunking noise and clutch remained at floor. Could not shift in to any gear. Slid toe of foot under clutch and popped it back up. Was then able to engage gear. Uneasy at this point. Any thoughts about what I should look for as potential problem(s)?
