JohnnyI think you are on shaky ground. Cooling off periods don't usually apply to normal orders (they apply to some finance deals like life insurance, or tomail order/internet purchases). They also apply to certain types of car finance, but the cooling off only applies to the method of finance (ie I've changed my mind about HP, and would rather do lease purchase or cash purchase) but the cooling off doesn't normally give you the right to cancel the deal. Whether money has changed hands or not is beside the point. By signing the order form, you have committed to a legally binding agreement which is enforceable, ie the dealer could force you to take the car.In reality, I would tell the dealer that your circumstances have changed, and you are no longer able to go ahead. Bearing in mind their legal rights, just offer the dealer an apology, and say you will come back as and when. It is highly unlikely the dealer will pursue you on this, but bear in mind that, in theory, they could!!
