I had a stint on a 3Ciii, 1979 'V' reg with the powertrain transmission, fantastic machine. Only wish i'd somewhere to put it, i'd love to get one!
Biggest issue I had with the 3C was when changing gear, I found the 'dump' pedal close too close to the brake pedals, and got my boot stuck on the pedal!
I was also taught to watch the angle of the 6:1 when loading MOT or similar loose material. If the top edge of the front bucket is allowed to get too horizontal when the loader arms are at at almost full stretch, material in the bucket can spill over the top edge, landing on the bonnet. There is a grille towards the front of the bonnet, should a stone fall through, it's not unknown for the cooling fan to then spit it clean through the rad!
