Installation wasn't bad at all.. if you have the tabs in your 1/4 panels already its REALLY easy, as that was the only semi-difficult part of the process for me. It's detailed pretty decently in another thread I think, as I took several pics when i was doing it. I have zero uphulstery experience, and I was able to attach the fabric to the wooden header without a problem, everything is marked and laid out for you. (so easy a caveman could do it! ) As for storing it in the trunk... that ain't happening with my car, because my fuel tank is in the trunk and takes up too much room. it would un-install easily though, as the tubing simply slides together with snap connectors, and the fabric unsnaps at the back, then is rolled up on the header bow it is attached to. The header is obviously as wide as the top of the windshield, so it should be pretty easy to tell if you have adequate trunk space to store the top. (about 6 feet I think) I'll be perfectly honest with you though, i NEVER take mine of now, and if I do, I will take it off as a unit, and sit it on the garage floor assembled. Seems much easier than dismantling the whole thing anyhow.
