Misterbonkers: I should have been more succinct: The cab (429) is wholly inadequate as a police cab specifically because of its payload/space in the back. Less of an issue for HEMS - though I did DD on it for both these roles several years ago and it didn't meet our specs then for HEMS config. Perhaps something has changed since then.
In addition ANYONE who becomes the lead customer for something like this - takes ALL the hits whilst it beds into industry. He has a double whammy on his books - good luck.
I have absolutely no doubt (with its pedigree) - it will settle in nicely as a private aircraft or a light utility for the energy companies.
