Easy tiger - think the point is that OZ is a bit of a heap (can't detect an ex-Go employee here can we???). Admittedly some of ezy's a/c aren't in the best of nick, YC for one looks like a patchwork quilt with all the rivetting and the lack of livery - flies nice though.
Oh well, life will be ok in Essex when the 700 arrives (and we swap them for some of your aged beauties!)
