With some amazing villages and attractions in the surrounding area of Sevilla, renting a car is the best way to explore the region at your own pace. Among the places worth visiting are the roman ruins of Itálica in the area of Aljarafe and Santiponce. Just outside Sevilla is Carmona, a cute small town, home to a roman necropolis and a picturesque center. Also you can visit Ecija, the "city of towers", or the town of Alcala de Guadaira where there is a castle with 11 towers, eight dolomites and beautiful pine trees.

A little further away is Jaén, known for its olive oils; Jerez de la Frontera, home to the world famous riding school: Royal Andalusian School of Equestrian Art, and known for its sherry and the bodegas; and the coastal town of Cádiz, the oldest continuously inhabited city in the Iberian Peninsula and possibly of all southwestern Europe. 

If you want to rent a car in Sevilla, or anywhere ells, compare prices from different rental companies. This is best done through the internet, also investigate any special deals the company may offer. If you book at your destination you may often be able to negotiate the price.

If you are not traveling alone, make sure your partner is also registered in the contract to be allowed to drive the car. Often an extra fee is charged, but again this may be negotiable.

Inspect the car when you take delivery, and make sure that any scratches or dents are registered. The same applies when you return the car.

Read the contract, and make sure that the boxes you want are marked with your initials, this is important in respect of the insurance cover you are getting. Save a copy of the contract.

Also observe the rules that applies to drive in Spain, they are not all the same as in the rest of Europe, and if you are from outside of Europe, in most cases you will need an International Driving License.
