Hi everyone Have had my SLK about 5 years now. Still love her. Had a new gearbox put in by Mercedes in Alicante a year ago, not cheap, but everything else still works so it needed doing. I have an issue with the roof. It works fine, but is getting slow to release the front latches. I am sure the cables need tightening, but not sure how to do that. No issue with the operation once it's disconnected at the front. Goes up and down fine and fast and is watertigh. Ideas please.
