Nicholas Cleak's 1967 Sunbeam Imp Sport, bought 1972, driven 40 miles a day from then to date ! It has covered 230,000 miles now. Turbocharged in 1982, various fuel systems tried, now on fully programmable electronic fuel injection and ignition.
Neil and Anne-Marie Lewis, Impressions March 1994:
"[...] one really quick car, [...]. It humbled most of the cars out on the track at the same time as us, until fuel starvation and a sticky wastegate intervened!"
