Definitely not Japanese!! Ive got a TD5 90 defender – All the claims about the electrics and ECU being fallible to faults etc, have been proven to be completely unfounded. The Defender will be easier to work on yourself and relatively free of complicated systems such as the air suspension found on the Discovery. Motorway cruising in the defender might not be as comfortable as the discovery though!?
If it were me, and I was ferrying kids around etc, I'd probably go for the Disco. BUT, I'd be always wondering how good the defender would have been.
Sorry – not much help
