They are all 15 years old at the very minimum. No questions asked as you can't insure anything newer. Post people who have these cars are punks who do nothing but stunt and speed.
However there are some guys who import cars, really do some nice work on them are safe on the roads and use the track.. Though that could be said for any cars.... RHD cars however are mostly associated with ######bags.
Pedals are all the same, obviously you're shifting with your left hand rather than your right. Turning left at first from what I hear is sketch at first but you really hang the hang of it....
Edit:
Parts are quite easy to come by now. Tons of these cars around Alberta so it's not so much an issue anymore.
