Robin nest with eggs in my car

Hi, yesterday my partner and I realised we have a nest in the grill of our car which contains 6 eggs.. my partner today noticed a Robin tending to it so we're assuming that she's the mummy..  

Obviously we need to use our car and don't want to cause stress or harm to the nest and we are unable to access easily to remove in one piece.. does anyone have any advise on what to do ? 

We will not use the car if we don't need too !
