I hope it's OK that I ask several questions at once, because they are about different cars...
#3 - is it Ford powered? Judging by the cars around and my memory, which nevertheless can't remember any other moments.
#9 - French hillclimb vehicle?
#11- we have already established that it is a small displacement Japanese formula, but is it Honda engined?
#17 - in my opinion it has quite an unusual styling for an LHD car. I would expect something like this to come from South Africa od Australia. Maybe this one is Canadian?
