Dude, I drive a Miata, and a 1st gen rx7. I can think of maybe 2 times I’ve needed to drive my husbands car (which is a veloster, so not terribly large either) in the 8 or so years of Miata ownership. At least one of those times was because I didn’t want to drive the RX7 from San Diego to Los Angeles with no air conditioning, no power steering, and a relatively heavy clutch, in the middle of summer, in rush hour traffic. Not because what I was picking up wouldn’t fit in the rx7.

What exactly do you need to do multiple trips for?
