Well, just over a week into ownership of a 4.2 SC and probably 100 miles or so of mixed driving and I've got the dreaded engine management light on. The code reader is saying 'catalyst efficiency below threshold'. it's soon to be returned from whence it came in the hope the non LR dealer can sort out this baptism of fire!
Updates to follow as and when if anyone's interested - oh for the joys of a return to uncomplicated Defender driving.

Which car did you end up buying?

not had that one yet !!!!!!!!!! how many miles has it done?

I think someone else was talking about that recently and mentioned failed cats but they had done 150,000 miles or so on theirs.
