Yeah alot of closet mardigras like complexes, lets leave it there!

In terms of simplicity and performance there is little to fault an A series.
More modern engines are complicated, harder to maintain and rebuild.

I believe bio-fuels will be entrenched in our future from bacteria or algae type
organisms and bastards like Agri-Corp Giants (eg Monsanto).

Will we be driving our own billet blocked bio-diesel/alco retro customs in the
future? Only possible if CNC billet alloy blocks become affordable.
Either way It will be great to look back if we are lucky to live to old age to
reminisce about what crazy things we thought.
