Peking to paris

Just beginning to get my head around the fact that I am driving the peking to paris rally next year. Went to look at the car yesterday and it is nearly ready to bring back from the garage. Took it, 1938 Chrysler Sloper Plymouth for a spin. It has 3 gears and is a bit different to my Audi. Can we do 8500 miles in it, two girls?!
