Bigger engine (335bhp), revised suspension, limited-slip diff. Trapezoidal grille now wider at bottom and has driving lamps protruding rather than recessed - this until revised 1973 model.

Genuine wood and leather, of course, plus power windows and an air-conditioning option. Replaced by 603 in 1976.
