I've done 4 over the last 47 years or so. 2 101 Spiders, Sunbeam Tiger, Saab 900 Cabrio. 2 Vinyl, 2 Robbins stayfast. All were for daily drivers. It is a finicky job, adjusting here and there over and over for millimeters. The worst part is refitting all the trim. Not a hard job but time consuming. I’d give myself a B+ For workmanship. Not bad for a driver. I’d want a professional installation for a show car or high dollar restoration. In complexity, I’d say the S2 is between the Tiger and the Saab. I’d also vote for the zip out rear window. Unzippered, the window lays flat when the top is down, which I think will make the window last longer, no bending or folding, fewer scratches, easier to replace just the window down the road. I’d also get a canvas over vinyl, looks a lot better and is easier to work with. IMHO, you dont save enough to justify the vinyl. The canvas tops fit better, I thought. There is an excellent top installation guide available on the board. It will be helpful in talking to installers, if you decide against DIY.
