Anyone that has owned a defender and actually used it off road...
...has probably got rid of it by now and got something Japanese instead.
My factory hilux surf required nothing much more than a roll of gaffer tape, some heavy to beat on it form time to time, oil and fuel to keep it running and it consistently out performed defenders and disco's on and off road, modified and unmodified in the sort of classic terrain of north wales.
The only thing that defenders are good for these days is something to fiddle with on a sunday afternoon.
Also, as noted previously, an AKM is nothing like a Landrover in that they are simple and reliable, always performing when needed and keep on working with no maintenance forever.
The AK74 is simply an AKM made to shoot the smaller 5.45mm round and offers virtually no other improvements on an already excellent design.
The defender had a good run but it's time now to let it go.
