Get it. For $100, if it's in good shape and complete, that is a great deal.
If you don't like the color, you could sell it and make a profit towards another top.
I found a almost new soft top on Craigslist. Complete with frame and door surrounds for $200. It is kahki, but I wanted black. I bought it anyway and put it on the Jeep. I like it better than having a black top.
