This is interesting, because there are some owners (including myself) who want paddle shifters but can't have. So do you say that if I buy the paddles (or a wheel with paddles on) all I need is a reprogramming?

If you pay the extra £110 for sports auto you get steering wheel paddles and changes to the software that prevents up and down changes during manual mode changes so you can redline the engine if you want. You don't get a different gearbox, just paddles and software changes.
If you down shift with the standard software gearbox the revs are increased to match engine speed with the rotational speed of the lower gear. On the sports auto the revs are increased further to give a sporty blip on down changes.
