That depends where you plan to wander. Downtown Saint John, about 9 miles from Saint John, NB Airport (YSJ), can be difficult to drive in. Make things easy for yourself by going for something small, fuel-efficient, and simple to operate. Keep in mind that Saint John is a handy base from which to explore some of the snowfields around Saint John County. If your trip is more about tearing down the open road, then you may like something with more trunk space and legroom. What about a full-size car or a standard SUV?
