Land Rover Series IIA

"Many Land Rover historians consider the Series IIA to be the best of the Series models, it exists in a Goldilocks zone between refinement and simplicity – before the crack-prone plastic dashboards of the Series III but after some engine and transmission improvements over the Series II.

Land Rover used the Series IIA as a transitional model between the Series II and the Series III, the lights were moved from the grill to the front wings in 1969, a new diesel engine was offered (closely based on the 2.25 litre petrol engine), and in 1967 a 2.6 litre inline 6 cylinder petrol engine was introduced (for the LWB models)."
