it sounds a good idea. i went to st tropez in the summer this year and took a day trip to monaco.was awsome walked round the whole track and at the time i went for 30euro's i was driven round the track in a ferriar (sp) 360convertible was amazing.however..... when i went on holiday we drove from Leicester to st tropez,using the euro tunnel.we were in a saab 93 convertible turbo,and took us just over 11hours to get there with one 10min break.and that was doing 80/90mph on the toll roads all the way down.so would take forever in a cinq.plus doing it that way cost about £70 in tolls,plus filling up costs on top.also accomidation in monte carlo is very very expensive and would be twice if not triple on gp weekend
