as a country bumpkin, 4×4 are pretty essential. Further more, having a decent one with a decent engine such as the defender we have atm is worthwhile… why?
1) used as a supply vehicle for the regular moor fires
2) used in a logging business
3) just about the only type of vehicle capable of launching a boat at the local 'free' slipway
4) diff lock and good driving skills get it out of snow, to drag/ winch you environmental wallies out of snow drifts, ditches, etc so that you can get to your internet-connecting device (presumably a blackberry)
5) it's made of scaffolding and sheet steel. Very little hydroforming operations, or niche coatings, or exotic materials here! So, manufacture is not half as environmentally harmful as your modern estates, hatchbacks, etc. It may produce more CO2/NOX/SO2 from combustion BUT simple manufacture means that less cyanates, cyanides, bromides/ bromates, lead compounds, Al- compounds and many more are released.
How's that?
