A cheap and quick way to the south of France

Although I personally prefer to ride here we had a group arrive last week with a car tranporter trailor and 4 bikes on board and yesterday I saw a german registered car with 6 bikes on a car trailor. The big advantage of this is that if you shift drive you can get from London to here through the tunnel in about 14 hours and as everyone takes a turn at driving noone arrives tired. By using this way you can get 2 extra days riding here , something worth considering. as most people only seem to get 7 or 9 days off for good behaviour.
