Thanks for all the feedback. Sounds like I might fit in a TR. Actually, I have a convertible at the moment, a '61 E-type flat floor roadster, which I modified to fit. I yanked the pedals, and with help from my cutting torch, heated and bent the clutch and brake pedal arms laterally to accomodate my generous (size 13) feet, and then relocated them on their respective shafts. In later years, of course, Jaguar depressed the floor plan to accomodate feet such as mine. I fiddled with the seat rails and went to a smaller-diameter steering wheel, and am now able to drive the car quite comfortably, even with the top up. Oh, the things we do for love.....
Be careful, though, about assumptions that Canadian drivers have to cope with many obstacles in order to enjoy their high-zoot toys. There are numerous gorgeous winding highways up here that are sparsely patrolled by the local constabulary and where one may, shall we say, let the dog off the leash with impunity. But not in January...
