I have the SWB 3.2 AUTO, had dscovery's prior to owing the Mitsi and there is no comparision to the Land Rover, I use it for work and mainly for towing, cant fault it at all, good solid car that handles really well, gives decent fuel ecconomy and loads of torque.
I think most suffer at some stage with the head (that AFAIK) is their only weekness.
I'd certainly buy another.....
