A good one, Saffy, here's mine:
Tommy Douglas - the "people's car" a VW of course, preferably an older Beetle.
Terry Fox - easy, a Fox-bodies Mustang GT convertible to keep in touch w all that country-side he trekked thru.
Pierre E. Trudeau - he'd have 15 private cars, mostly exotics, salted away in his secret garage, but would ride in the taxpayer-provided Chevy w door sedan and claim he was hard done by.
Sir Edward Banting - a '59 Cadillac ambulance with "Nobel Prizes Foreever" painted on the side above the picture of an Iron Lung.
Dr. Suzuki - easy one, Toyota Prius.
Lester Pearson - a RollsRoyce to go with his natty suits and bowtie (no Chevies cause it's a fancy bowtie).
Don Cherry - this one is wide open - a Magnum R/T w 22'spinner wheels painted orange with black racing stripes and a huge exhaust.
Sir John A. - any minivan to carry his booze supply and a lifetime railway pass.
Alex G. Bell - a Lexus LS430 w Navi, cell phones (many), GPS, voice activated radio and climate control and the biggest I-Drive system in the world.
Gretz - probably need Hummer for his family plus a Zamboni for daily errands.
And, Saf, ya did beat me out - I think I was dead last but it was close between Snowy and me, but I lost.
