I think you'll find that in 1982 Defenders were yet to acquire the name and were still simply badged as Landrovers.
Ive not checked but that date sounds like it was the crossover between the old series machines and the defenders. probably the thirsty and underpowered V8.
Perhaps OK for some off-roading but you'd probably be a lot better looking for a 200TDi or 300TDi if you can stretch to it
