I've always used Ace rental cars - and most recently (1 October) booked a four day car hire with them from Dunedin airport for $24/day (a Nissan Tida).

I've just tried to book the same car for the same period of time at the same location in January next year - and the quoted price is $57/day! That's a massive increase, which doesn't seem right. Can anybody shed any light on this?  Thanks!
