I have a NOAH cover for the PT Cruiser, and it worked well but that car is not a ragtop. I bought a $40 +/- fits-all cover from a parts store locally for the Sebring Convertible, and it was made of similar material as the NOAH, it just wasn't taylored. The Sebring leaked, but the cover was water resistant enough to keep the water out of the inside of the car. It also had a vinyl top, and not a cloth top.

All of these covers were NOT waterproof covers! do NOT get a waterproof cover, your vehicle will stay wet all winter under the cover. The cover MUST breathe in order to dry off. A water-resistant cover like the NOAH cover is a breathable cover, and will allow the cover to dry on a dry day. Before you stor the car for the winter treat the top with RaggTopp.

I intend to buy a NOAH cover for the Crossfire when I get a custom cover, in the mean time I have a garage, and I have a fits-all cover that a friend gave me that I use as a dust cover.

BTW, I got my NOAH cover from; http://www.autoanything.com

May I reccomend that you are better off putting the car in storage, as long as you can start it and drive it a bit when the weather is nice (at lest once a month). This is important to keep oil on the cylinder walls, and the battery charged.
