Howdoo, Andy.  Congrats on the new arrival and welcome to what is the best source of 'Meega info available, virtually real time, on t'interweb!!
The car on e-bay.  Like others have said, something does not add up to me.  
The car is being advertised as a Police spec MV6.  The miles seem a bit off, to me.  Contact West Mercia HQ, asking for the garage/fleet manager, and ask nice for a run down of the car over the 'phone.  Explain why you are asking and theres a good chance that you will get an honest answer.  
It has the manual heater controls - OK so far.
No rear spoiler - still OK
No sunroof - still OK!!
Alloys - If it is the real deal Police MV6, then its got alloys that are non standard for a cop car.  The real ones are steels and hubcaps!!   :-/
Speedo - as far as I can see, does not have the IRS calibration sticker.  Ask for a close up piccy.  If its got 5 mph increments and no sticker, then its either not as advertised or its got a replacement speedohead.  I would suspect the latter!!
As always, Caveat Emptor, and only spend what you can afford to loose.
