Hello, my girlfriend is driving a Smart ForFour 1.1i and I need some information about it. Our anniversary is coming soon but since we will not be able to be together at the time I want to surprise her by hiding a gift in her car. The problem is I can't measure if the box will fit without it being suspicious. Can somebody who owns a car like that please tell me how big the compartment under the front passenger seat is? Or if you can give me any tips on where I can hide a box with the size of 23x15x8 in centimetres, please?
