Hold on, chaps! The new Mini is not revolutionary, nor even evolutionary in the sense of doing something known but doing it better than before. It's a fairly conventional modern small European car, similar to any number of other vehicles in the same size and price range. I have no doubt that it's a very good automobile and probably fun to drive, but apart from the superficial similarity in shape (but not size; the new one isn't very small), it has little or no connection with the original Mini. I doubt that it handles any better than a small VW, Renault, Peugeot, Skoda, Fiat etc. etc. or even European Ford (none of the comparable vehicles is available in the U.S.)
In contrast, the original(1958-9?) was revolutionary. A mass production inexpensive vehicle with transverse engine, front-wheel drive, plenty of space for people in the front and just about tolerable for two in the rear (better than some American cars of the period that were twice as long!), within a few years with hydrolastic suspension (amazing for a car of these dimensions). Those were firsts. And of course it had handling that placed it with the most expensive sports cars of the day.
My first car was a new 1968 Mini, basic 848 cc, no frills apart from underseal. It cost 640 pounds, well under $1000 at today's exchange and only perhaps $1400 even then. No, its acceleration and top speed were unimpressive (although the engine flexibility was extraordinary), but of course you didn't need to slow down for bends! It was fun to drive in a way that very few other cars of the era were.
