So I am planning on moving to France for a couple of months in the summer and working in Vineyards. I will be living in the Loire Valley near Tours, and I am pretty confident that my 126 Will make it to this destination. If there are any failures on the way I know enough French to get problems sorted.
However In August I am planning on leaving the wine and Driving from Tours, France to Idanha-A-Nova, Portugal.
Google thinks it will take approx 13 hours but that is probably in a modern car and I would take my time and drive this over 4 or 5 days. Then I will stay in Portugal until I start missing Blighty and hopefully return with my Fiat 126. ! (most likely on a ferry from Santander to Plymouth)
Has anyone els made any long road trips like this in their 126's? I know some people who did it in the 70's.
As my Fiat 126 is a Polski Air cooled I was wondering if there would be big problems with it over heating in Spanish and Portuguese heat.

Any advise would be much appreciated!
A lot of people are saying I'm crazy to suggest this.
