I don't believe any of you - except the guy talking about drama.
I bought my DI with 6K miles on it. Within the firt 2 years the following was changed under warrenty because of leaks.
Power steering hose.
Main crank seal
Transfer case exit seal
Rear side window seals - left one twice
Back window seal
Intake manifold still leaks coolent - I tightened it - now only leaks enough to stink.
My thought is this. During the time that LR designed the Disco1, with very little funding, they hiredco-op students from the local high school. To celebrate their "cool" summer work term the visited the pub every night for a few pints. The next day they returned to work and selected materials (rubber) that was easily available without concern of UV protection, chemical resistance, and fatigue life.
Thus we have what we have - a good excuse getting out of the house, playing with power tools, and getting stuck in the mud.
Now can you say the same for a Honda CRV, or Toyota RAV4?
