After a decade of driving the fab xsara pic diesel I am shocked by the improvements made to the heating system on the c3 pic, while the xpic failed to warm the footwells in winter this c3 has the urge to do it all the time, I am constantly aware of hot feet no matter what the heater settings are, so much so that I am coming to the conclusion it is mainly radiated heat from the engine entering the footwells, it is not unpleasant, just unusual
