I remember those days, Isettas for £50, Nobels for £200, Messerschmitts for £200 (with a spare engine, manuals and set of factory tools). You could go to car shows and speak to people who would have engines and other bits in their sheds and would just give them to you, like I had with a four wheel Nobel once ...
My first T&T'd Isetta only cost £500.
Nowadays, it's all, how much is it worth and what's the fuel consumption - how times have changed!
