If you are thinking hill climb proxy, let me know, I'm sure Luf would allow a run up the Burnaby Grind, but cars over 5" long and 2.25" wide might hit the scenery. Those rock walls almost overhang the track and many good runs have been spoiled by offs with bigger cars. The turns are quite tight as well.
The smaller PanAm cars would be fine, but the big Detroit sedans would never make it, or you would have to be so careful it would be pointless. But, of course, since fun runs are "point-less" anyway, maybe we should at least try when they are here. Could at least get some good photo ops.
