The backpacker market for good rental cars in Christchurch is keeping up the demand here in the Garden City. So, both out at the airport, and closer to the center of the city, rental car businesses are finding they are getting the tourists they need to sustain their ventures. Rental car businesses at the airport cater mainly for the upper end of the market, but near Cathedral Square there are other rental car companies which sell to the lower end. A backpacker will call in, wanting a cheap hire car for a week. It is these businesses, near the square, which will help himand his friend make their trip — and then buy back the vehicle when they return, ready to fly home again.
