The theme is the Fiat 500 Abarth of the 1960's. It featured a stroked and bored 650cc engine that required so much cooling, they used the permanently wedge the boot open. Note the nudge bar/crash bars, and the small dashboard.
It is a Spanish SII with a SR190 engine.
I hope you like it, and if all is well, I'll be at Lincoln on it (I'm just off for my first ride......)
