Irismarie, are you planning to get a manual chair or a power chair? All of the above answers refer to a power chair. Have you looked at a scooter as a low cost alternative to a power chair, at least for the early stages of walking disability? You need the ability to stand and transfer and reasonable arm strength to use one. A scooter is fine for quite steep hills as well. I've been using one for about 4 years.
By the way, my daughter lived in Vannes in Bretagne with a French family and attended high school for a year. I visited her there and then drove to Milano where we dropped her off to take a train back to Vannes. We would have passed quite close to Valeilles on the way to Toulouse. My memories of the beautiful countryside, the vineyards, the people, the amazingly good food, the cheeses, the crusty bread and of course the wine are still fresh. Oh yeah, my memories of the French drivers are also still fresh.
