IN SOME overseas markets, the latest-generation Prado is known simply as the LandCruiser, underlining the importance of the sub-brand as one of the definitive off-road vehicles available today. And in this respect, the 150 Series Prado does not disappoint, since Toyota’s engineers have merely improved on what was one of the most 'go-anywhere' models around. But how much better on-road is the fourth-generation ‘LandCruiser Light’ (as the series was originally envisaged to be in the 1980s)? Everything has gone up – including pricing – so much rides on how successful Toyota has been in updating what has become a 4x4 icon in this country.
