I once beat a colleague of mine driving is Porsche 911 Turbo in an impromptu street race in a deserted semi-demolished housing scheme somewhere in central Scotland, in an elderly Citroën Dyane.

Yup. With its 602cc engine, it absolutely wiped the floor with the 911. Totally unfair fight, fully 30 seconds faster per mile.

I probably shouldn't have goaded him into the bits that still had speed bumps, eh?
