We are planning to visit Verdon Gorge in September 26th. We plan to hire a car from Marseille and travel to gorge, and return on 29th. We are calculating that the expense for a car per day will be around 30€ (Rent+GPS). And we ll have to bear the fuel expenses. But we have seen a thread in TA warning against thefts and other hidden expenses. Is this too adventurous a plan? How can we make this work? What all things should be taken care of? Any references for a trustworthy car rental agency?
