Prior to this, had sent all hydraulic cylinders to Klaus for a rebuild, and reinstalled. Roof worked great for a year after that. Last year when I took it out of storage, tried using toggle to automatically open roof. Deck lid started to open, then froze. Decided to just manually open and close roof til I could inspect fluid level and integrity of hose fittings. At end of season, was going to put it back in storage, and when I tried to manually open roof, found that final lock down of deck lid wasn't clicking. It would click if I raised the deck lid off it's seat, but at over 10 mph, alarm would chime. I put roof back up and drove to storage without any chimes looking a lot less cool.
