We will be at our villa from October 2016 until March 2017 and would like to have a car to use. Does anyone know of any good LONG TERM car hire deals.

For that length of time you could consider buying a car and selling at the end.

If you do rent then speak direct to a rental firm (not an agent) and negotiate hard - they should be pleased to have your business in the winter.

Try Zitautos they do a good deal have used them last 10 years, good service and price.
