Well, you'll get everyone calling it a Smurf for a start... :lol:
I get the impression that there's nothing wrong with them, as with all Jap stuff they're reliable but upgrading them can be more difficult/more expensive.
The major advantage with the Disco is that you'll have no shortage of spares (loads being broken for parts) and any country garage will be able to keep it healthy. There's nothing on there that would baffle a mechanic used to Defenders, and large chunks of it wouldn't cause much head scratching for a Series 1 expert from 1948.
Most service items are easy to get at and the design is such that you only need axle stands if a wheel has to come off - there's enough space to crawl underneath without needing to jack it up. It's also a good deal more compact than it looks, the wheelbase is the same as the latest version of the Mini after all.
