I didn't take you as being sarcastic and my reply was supposed to be light hearted! I really do appreciate all your advice. I'm hoping BBA will be able to shed some light on the matter. While I'm not unhappy with them, they won't claim this was their best job as they 'lost' the hand delivered units in their system (luckily i had taken pictures of the units with serial numbers etc so they could ID them) and on pick up they couldn't give us any paperwork due to their computer being down. These things happen and all is forgiven when the car starts!!
