well said Lee,
Anyway how would your insurance be invalid, and how could they prove it , car would be in Daddy's name and if you did have a bump you would say that you were lending it.
buy his some flowers and say sorry.
Seriously buy him a bottle of whisky and leave it on the front desk as an applogy may take him by supprise and he will let it end.
or vist it him with the police to say sorry this way he cant hit you.
when I start the car in the morrning I can hear a running water sound coming from under the passenger side of the dash also have found that the carpet is a bit wet too, it stops when i give it a few revs.
Any one else had this?
