The first generation of the Defender, also known as the One Ten, lasted from 1983 until 1990. It was available in 4 different body types: two door station wagon, 4 door station wagon, 2 door van, and 2 door pickup truck.
Engines ranged from a puny 62 horsepower I4 to a considerably better 134 horsepower V8. All transmissions were manual, and all were 5 speed with the exception of one 4 speed.
The Defender name was adopted for the second generation in 1990. They came in all the same body types as the original, but with the addition of a 4 door pickup truck option.
The engine options on the second generations were much better, ranging from a 107 horsepower I4 to a 182 horsepower V8.
A four speed automatic transmission was added to this series of the Defender as an alternative to the two 5 speeds and one 6 speed manual.
The Defender was changed significantly for the 2007 model year, mostly to meet safety and emission standards.
This vehicle is an old-school throwback to the way automobiles used to be made. Each Defender is assembled by hand, and it does not have unibody construction, so it can be disassembled down to the chassis by anyone with a decent set of standard hand tools. This makes it especially popular for military uses.
This vehicle retails for between 20,000 and 30,000 pounds in the U.K. Those imported to the US would be over double that in US dollars, based on the current exchange rate and import charges. You can sometimes find them used on eBay.
