100mm is the lowest it can be any point, intrusion beams in the doors, child seat restraints. Depending on the rule it comes in under dictates additional items that need to be done e.g emissions.

Generally Fords are easier to comply than Jap stuff as things like the tyres meet the Oz required spec etc. They are also supposed to have an unleaded sticker put inside the fuel flap.

I would be interested to hear about the 500 too Aaron when you get some time.
