It only takes me about 5 minutes and that's without rushing, but I am picky about how I take it down so it goes up faster. Plus when mine's down, it looks all nice and neat rolled up on the rear bar tucked down just in front of the spare tire... all too often I see Trackers running around topless with the top completely taken off, snaps and all, and just wadded up and stuffed behind the rear seat!

It makes me laugh...
Here's how I do it, not sure if it's the "right" way to do it or not, but it works for me:
Release front clips and swing front section back sunroof style.
Unzip rear window and let it lay down against the inside of the tailgate.
Un-velcro the side windows from their frames and unhook the rear corners.
Swing sides up and lay them on top of the rear roof section(leaving the tension straps on either side of the sunroof connected and all snaps still snapped, even the two on either side of the dome light).
Unclip the front section from the front frame and lay the fabric back on top of the rear sides. Clip the front frame back into it's closed position.
unhook the rear tube's lower legs and swing the main rear hoop forward all the way until it's above the targa section.
Take the fabric hanging down behind the targa and fold it up over the main rear hoop again, then unsnap the side tension straps and use them to wrap around the fabric to hold it in place(you have to give the strap a half turn to get it to snap again).
Now you have a nice compact roll on the rear hoop. Just unsnap the two snaps on either side of the dome light and lay the whole hoop back just in front of the spare. It goes up really fast from this configuration. Just do everything in reverse and you're covered from rain after the first three steps!
