Nowt down South
I've not seen one in London or Essex, and this despite my local dealer a few minutes down the road reporting to have sold six in the same morning that I went for my test drive.
Note that the test drive was at 11:00 ... so if they opened at 09:00, that equates to one car sold every 20 minutes. Needless to say, I didn't buy from a dealer with the kind of attitude.
