when i bought my targa soft top, i used it once on awhile then i would use the hard top.. i bought a wall mounted bike rack (you can find it @ Lowes, Home Depot or Walmart....and installed in on the wall.. i keep my hardtop on that rack and currently have the soft targa top on the car, so it will keep its shape
the rack is mounted up on the wall in the garage, kinda up and out of the way, you can walk underneath it w/o crashing into it with your head...do this and your top will stay in one piece..
