I agree with others on several points.
(1) A C182 is ideal for the mission spec and one of the nicest to fly aeroplanes Cessna have ever built.
(2) Pilot Centre at Denham are decent people who look after their aeroplanes well.
(3) Their C182 is a pretty good one, I've flown it (albeit several years ago).
One warning is that the CFI at Denham tends to the over thorough perhaps on checkout requirements, so budget for that.
