Good outcome from a bad situation, should never have happened ps, thanks for the info.
I think their is merit in MrB's procedure of putting anti seize on the g/plug threads, at least if they fault after some years
they stand a chance of coming out easier and with no damage (even on new motors at time of purchase.).
6.5l/100 is quite good economy, at least that is a plus for the car. I found with the diesel Fozz that it was getting better as it got a few more K's on it and I agree with your comment re gravel road driving, the Fozz was outstanding and this sure footedness is one of the reasons we'll buy another.
Good info and outcome also for plume although I think they ripped you a little for the $200 fee.
