I totally agree with those such as DeeJay who have already urged you to eschew the French Autoroutes in favour of the Routes Nationales.
I never found my Morgan to be particularly enjoyable to drive on a motorway; one of the real joys of my experience of Morgan ownership was that it persuaded me on most occasions to opt for the scenic route. As a result, in the 5 years we owned the car, we got to discover and enjoy much of "la France profonde", which we would otherwise have missed completely as we flashed past on the motorway. There are so many wonderful places to see and visit off the beaten track, and in the Morgan, we always received a warm welcome wherever we went
Mind you, for any forays onto the Autoroutes, I highly recommend the tag for motorway péages as per MJF and others.
