Probably a 911. It's a true sports car that you can use as a daily driver and that has very high reliability ratings (unlike the SUVs you mentioned, which are "so so"). Porsche 911 reliability is outstanding, the rest vary a lot.
Of course, if you really need room and storage, you'll have to bite on an SUV--but I wouldn't buy a vehicle just because you need it 5% of the time.
Since your choices are at odds with each other (sports car vs. SUV) you'll have to decide, before you do anything, which percentage of use is likely for each type.
If it's 50-50%, then your choice is difficult and it may come down to a) reliability b) closest dealer or shop c) who else you might have to please in the family.
