I had great fun yesterday carving back roads with a friend and fellow air-cooled enthusiast, and had a perfect opportunity to compare my '85 3.2 back-to-back with his early 80's 930. This was my first time driving a 930 and, in short, it lived up to the hype. The car felt very similar to mine up to 3500 RPM, and then it felt like mine with an extra engine. This 930 does benefit from an aftermarket turbo and intercooler that pushed about 1.1 bar, so not quite stock. Once the turbo spooled, you better be pointed in a straight line! That was especially true in the sub-40 degree ambient temperatures that hamstrung his tires. But, wow, was it a fun car to drive hard!
I was, however, left with the impression that it would be difficult to enjoy this car safely and legally on our small country roads - much harder than my 3.2. Leave your foot in it and you're quickly pushing 100. And with a 4-speed vs. my 5-speed, plus long gearing, you don't get to shift as much. In contrast, I can run my 3.2 towards redline in every gear (once fully warmed up, of course), plus enjoy shifting at every bend, and still remain (relatively) legal. It's also far more relaxing in the 3.2 to push hard in corners. While the 930 is more exhilarating once on boost, corner-carving proves more stressful and difficult because you have to pay such close attention to where you are on the boost curve. So for my partricular driving style that favors technical corners and momentum cars, I'll happily stick to my 3.2 (plus I can't come close to affording a 930 
)
