I took the roof off for the first time the other day (Bought the car just before the winter) and, as you all may know, it's a bit of a PITA to put on and take off. The roof for the Elise is very similar to the Targa roof found on the corvettes, which have cam-handles so you can easily pop it on and off.
I rendered this really quickly, any reason why it wouldn't work? Because the cam-handle does the tighening and loosening, once fitted and tweaked, it would mean that you can put a dab of Lock-tite at the end of the thread, screw it into the roof and call it a day.
Let me know what you guys think
