Car rental agencies abound in Costa Rica. Renting a car in the high season ( from December to April) costs between $45.00 a day for a standard car and $70.00 a day for a four wheel drive car, including insurance. For the low season the rates are between $35.00 a day for a standard car and $64.00 for a four wheel drive car. During the high season you must reserve the vehicle in advance. Many roads become impassable for a regular car during the green season, and rental car agencies will tell you if you need a four wheel drive car. A major credit card or a $500.00 to $1000.00 deposit for the deductible is required. All cars carry the "Collision Damage Waver".
