I have a 2000 jtd elx
Check the Power Steering works correctly. While stationery, both in normal and city mode, turn it lock to lock a few times. Mine had the usual power steering failure and would come back to life, only to fail while turning right.
That cost about £700 to fix at the main dealer. Worth checking to see if thats been done. It's got nothing to do with mileage either, mine has only just done 60k
Again, check for cam belt, about £300 at main dealer, as you need tensioners etc but worth getting it done there.
Only other drama I had was the bottom hose on the radiator popping off one day. Could have been a diaster, but I know the smell of coolent and stopped immediatly ! Was a close one !
Apart from that, it's a cracking little car, will cruise at 90 with out trying which is quite amusing when you realise you are still returing 40mpg
Handling can be a bit strange at first, as the engine weight causes slight under steer.
