This summer I'm driving to Biarritz from London in my 3 door Renault Clio, with two boards. I haven't got roof racks and don't really want to get permanent ones (because of cost...). So I was wondering if anyone has tried the soft roof racks available? Are they easy to use? do they work on a 3 door car? are they suitable for long journeys on motorways etc? Any advice would be appreciated...there are so many out there and I just don't know where to start looking!
