Clearly it would be Mrs Nordic.
However as she has expressed no intention of ever sleeping in a tent or going to Le Mans, it would have to be Ms Halle Berry. I may however,have to invest in a bigger tent as she is quite tall.
I don't think she has any interest in motorsport, so could stay behind to cook, clean, do her make up in a car wing mirror and prevent pikey attack.
(Halle on the off chance you read this while googling before the Oscars, PM me details of your phone number and approx height, cheers.)
