My Grande Punto, Citroen C3 Picasso and my current Suzuki Wagon R+ all had/have electric power steering wiith no fluid involvement at all, in one of the current car magazines Practical Mechanics? there's an article on replacing faulty electric power steering, the Fiat set up shown is all based around the steering column, and looks a right pig to work on with servos and sensor, whereas the VW set up appears to be all incorporated with the steering rack, and a much easier proposition for anyone attempting to fit electric power steering to something else, whether or not you could get the rack to fit to a Gamma is another matter.
