Sorry I didnt finish the above, the company network was going to be turned off and I got 2 mins notice.
Its a 3 door, Tornado Red, no PAS and as it gets a full oil change (4 litres) every 3000 miles I suppose it loses 1/2 litre in that time. It has just this weekend started to lose water but judging from blue hue outside the expansion tank cap it seems it might be escaping from there.
