My thanks to "Ann" (without an "e") for sending me these pictures of her BMW Isetta. Ann is currently travelling around the UK in "ESU".
Its strange that I actually recognise this car from a Car Rally I went to in 1992. I took a photo of it which can be seen on the BMW / Isetta page. Ann brought ESU a couple of years ago and by sheer coincidence I recognised the number plate on another picture elsewhere on the Internet.
As they always say, "its a small world."
