Converted airfields are rubbish, you need something with a challenge like Oulton, Cadwell, Donnington, Brands GP... Think of them as practice and the chance to improve your craft, meaning you'll get more out of things like the 'Ring.
....Oulton, Cadwell, and Donnington are all far too far away for a trackday without staying the nights either side in grimsville. That's why I mentioned Brands earlier, and only the full circuit.
The 'Ring is NO place to learn how your car handles, the road will never give you chance to explore the limit - trackdays along with being tremendous fun, are the safest and best responsible way to prepare yourself for getting the most out of your car elsewhere.
....I hear and understand what you are saying but I don't completely agree - You don't have to explore the absolute limit to enjoy yourself. In fact, if my tyres are continually squealing or I'm getting wheelspin then I consider I'm not driving well. I'm not saying that trackdays aren't fun but more that I'm fussy about them and love the environment and dynamic of the road.
Why do so many car manufacturers use The 'Ring to see how their cars handle and perform? - The Nordschleife is a Mecca for chassis engineers from Porsche, BMW, Mercedes-Benz, and the VW Group. If a car works well on the Nordschleife, engineers will tell you, it'll work well on just about any road in the world. So far, I drive The 'Ring the same way as I do a fast B-road (at 23mph, as Nathan says
