Hi Mike
Try this site for City-el information:
http://www.ralfwagner.deRalf was very helpful when I was dithering about adding one to the Devonport Collection of Cr*p and Classics until a fear of something electrical and expensive going wrong made me see sense!
There was a chap in Essex - Harold Marfleet or something like that - who was involved with the school entries for the BP Mileage Marathons and had a City-el with a small petrol engine which operated on the "squirt and cast" principle and achieved a ridiculous amount of miles to the gallon.
Personally, I'm happy with my 87mpg Tuk Tuk and the 48mpg Citroen BX - but my wife always says that I have a low threshold of satisfaction!
Regards,
Nick D.
