I know, we were seriously considering going single-car (we also have a minivan), but (a) the occasional use pops up with less notice than a rental can be gotten (I should look into a cab option, but we're in a suburban area where cabs are very rare, but maybe it's easy enough to call for one, I've never tried), and (b) we want to hang on to the car for when our oldest son will be able to drive it in a few years, which would mean he can drive his siblings to and from school and other events, which would make life a whole lot easier!
