Cooper Cabrio luggage capacity

Hi there,

I'm booking a rental car for my wife and I when visiting Portugal. We were thinking of getting a Mini Cooper Cabrio, only problem is it's not a short trip so we will not be packing light.

2 full size suitcases, 2 carry ons and 2 normal sized backpacks. On top of all that I am 6'5"... Thoughts?
