Just come back from 2 weeks holiday in Kefalonia, staying in Lourdata. We hired a car for 4 days, we did look around at what was available and the cost. The best deal was from CBR car rental, which included zero excees. The office is run by a really friendly english couple, so everything is explained clearly, they also matched the deal on offer by the Tour Operators. Express car hire, the man in there was a right grump.
