I'm with Richard on the "they all do that" argument. But MMC have it covered on my 2 year old car as in the hand book it says "If the vehicle is left standing for more than 3 days then it is advised that a battery conditioner is used". So MMC do know it's bad.
I have found that the immobiliser will not unlock but after re-reading DaveW's post on this and using the 20 second rule then the car starts fine with 11.2V on the in car volt meter (which is the same as my test meter).
There is still no answer to my question though of "what the quiescent carrent draw should be?", I have asked the same question of the dealer but he has not replied so far.
I shall have to look into this further and find out whether it's the immobiliser, the clock or something else that's the issue. In my case it could be the battery as it is obvious that the battery cover has been removed many, many times before I bought the car.
Cheers

IIRC the dash clock in Mogs is not quartz & is a basic old 12v coil/motor style, it would be interesting to see how many milliamps it draws
