Hi I have found a great site for car sharing to France which is brilliant for me as I often go accross to my mothers place but not as much as I would like as the ferry crossings are so expensive. From what I can see from signing up is that you can either look for a lift to France or if you have room in your car you can offer to take someone else in yours and share costs. It's www.franceconnections.co.uk Hope it's of some use to someone and who knows, you might be giving me a lift
