Our Disco was great offroad, and not bad in the city. But the repairs. We babied our rig and at only 45K we had a main seal fail ($1600) and at 47K a gear box seal problem ($1400). We thought an extended warranty would protect us--it didn't, as even they won't pay for the full amount of these high priced repairs.
These are not cheap rigs. They should last. Improve them!
