Happy to say April MOT 2012 didn't cause me any undue worries.
Main things that you seem to need to look out for are:
That all your warning lights are working
Tow bar electrics (if fitted) must be working and in good order.
Your seat must be able to adjust 3 positions and be secure.
Door must close properly, with ease. (relevant to the Midas as the hinges do go bad with wear and drop).
All repairs must be done to a high standard.
Wiring secure and to a good standard.
Fuel lines not chafed.
Battery secure.
HID's (Headlamps) must be levelling and have a wash wipe facility.
Rose joints don't need boots...only greased swivel joints dust covers (which must not have any splits in at all now).
Inner CV boots are now checked.
All the best,
David
