Hi
Upgrades were reported as being, and improved Steering rack giving better feel, and modifications to the ecu to give better throtlle response, and of course changing to the OBD compliance. As someone reported on this forum before little modification took place during the life of the production run but when buying a 3200 its condition that is important not year, if you have a choice and can find one in the right condition, in the colour you like and at a price you can afford then year would then be the deciding factor.
