Car Rental here you can search Multiple sites for Cheapest Car Rentals. Costa Rica is a very small country and most tourist destinations are within a few hours drive of San José. Not only will you drive through beautiful countryside, but some small, out-of-the-way places will only be discovered by car. The adventure lover will appreciate the freedom to explore.
I do not recommend renting a car during the time you are in San José. Traffic and parking can be difficult and finding your way around is almost impossible as most buildings don't have addresses. Taxis are not only relatively cheap, but the drivers know where everything is. The biggest problem with driving in Costa Rica isn't the roads, it's the slow-moving vehicles (mostly trucks) that cause delays and the dangerous passes that frustrated drivers make in attempt to overtake them. You will probably have to make a few passes on double yellow lines if you rent a car and want to get anywhere fast, but use caution and drive VERY defensively. As there are few traffic cops in Costa Rica, drivers tend to be a little aggressive in their maneuvers. click on this links
