I am in need of a new softtop, it is now cloudy and cuts where the back plastic windows fold. A person on eBay is selling many new softtop for different models of Mercedes for around $350 (mine is a 1992 300SL). Now, I was wondering if any one here has installed a softop?? Is so, how difficult is it and is it something a "normal" everyday person could do?? I've gone to the dealer to get a quote and it cost $3400. Aftermarket upholster shop charges $1700 (850 for the top,and 850 for the labor). Any special tools I need?? Any help appreciated, thanks in advance.
