It is highly recommended that you rent a car on Vieques if you wish to explore the island. A lot of the best beaches can only be reached with a 4-wheel drive vehicle because the roads are dirt roads, are full of potholes and after a heavy rain can be pretty hard to get to.
It is not recommended that you rent a car on the mainland of Puerto Rico and transfer it to Vieques on the cargo ferry. The cargo ferry can be very unreliable and can choose to not bring your car over if something else takes precedent. Also the car rental agencies on the mainland do not typically allow the cars to be taken off island.
Below is a list of car rental agencies on the island. It is recommended that you secure a car before a place to stay because cars are in limited supply but high demand during peak renting seasons.
