IMHO the absolute nicest lookint set up is the autoform. It gives you about 4 inches more headroom, and it almost looks like the car is a coupe. It definitely looks like it belongs there.
www.autoformgroup.com you can see pics, or lots of guys here have posted their individual pics. The other popluar top is the "3-piece" stowable top...the benefit here is you can dismantle it and put it in your trunk. This you cannot do with the Autoform. I personally feel it does not compare looks/style both are about the same price...and both setups comewith everything, windows, bags, etc. Good luck!
