Hiring cars for disabled people is not an easy task, especially when you are looking for vehicles that the disabled can drive themselves. But looking into the matter we have come across some interesting info. on some companies, one which is called ASC.
It has all types of vehicles with different size chairs, lifts, swivel chairs and ramps to make getting around easier. The price ranged from about 50 Euro a day and limited mileage to about 140 Euro a week. They even mentioned that there was door to door service for a little more. This website is only in Spanish and the address that they have for their central office is in Toledo, near Madrid. But I think you should just try to email them or call them up and find out if they can help you.
Driving in Spain and its laws have always been "serious business" and especially for those who have limitations. Here in Spain there has been a big improvement with more and better highways, abundant parking spaces on the city streets and car parks specially marked for disabled drivers. But just one personal observations: the Spanish like to be the first to 'pop the clutch' and race out from the traffic lights.
