I meant to post this last month, however life got in the way. Whenever we go on holiday, we always take the wife's car. She has a Tiguan which has loads of space, and I have the 'smaller' NX. This year with a baby in tow, we had a bit more than we normally take. Usually, we put one case in the car, one on the back seat, however this year we had a bit more to take. I tried to get the cases in to the Tiguan, and it wasn't having any of it. I went to switch the cases with my parents as they have smaller cases. To my surprise, the NX's boot swallowed both cases side by side. A quick change of registration for the parking, and the NX was loaded up.
I was utterly amazed on how the NX took everything so well. We tethered everything so that it wouldn't move and made our way to Southampton. Just for reference, there are two large cases, a normal size case on top, a carry on flight case, holdall and a backpack. I could have probably still fitted a bit more down the sides too. The Tiguan is definitely bigger, and had more leg room, but cargo space, not a chance. Well done NX!
