With Madrid located at almost the exact geographical center of the Iberian Peninsula, Madrid is a good starting point if you want to rent a car and drive around Spain and Portugal to see some of the many beautiful and historic places and cities.
The infrastructure is generally good and especially the highways are usually in an excellent driving condition. In some parts you must pay to use the highways, but in most places they are free, and if you get to a stretch where you have to pay, there are always alternative roads without payment.
At Madrid’s International Airport there are many car rental companies present, including all the well-known international firms and some local ones. There can be price differences between these firms and sometimes it is cheaper not to rent at the airport. 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.
