Both incorrect, I reckon. Yes, it is LR105 from 1961, but it was used as the "mule" for a proposed MkII model. It was started in late 1963, but the management decided against it in 1964 , and the MkII was never introduced to the public.
It had a DB6 engine, upgraded mechanically, and the revised grille. The Rapide was a loss-maker, and all orders were cancelled.
