Popular all over Spain, demand for convertible car hire in Spain really ramps up as we head into the summer peak season. We recommend booking convertible car hire in Spain as early as possible and to start looking 6 months in advance and the best deals are released around this time and remain available until around 3 months before travel. You can still find the cheapest price for convertible car hire in Spain for last minute bookings, but you run the risk of demand outstripping supply and you may struggle to find a convertible model at all, or pay a high price for it.
