Hi Julie
www.viamichelin.com will give you three route options. Fuel figures are those given for my car. 1. €90 for fuel €29.55 Tolls = €119.55........2. €97 for fuel €14.85 Tolls = €112.85.........3.€95 for fuel €17.60 Tolls =€113.60
Not a lot between all three.
Hope this helps and drive safely
Neil
