I'll be flying into Gerona's airport (great deal - 10 euros for a flight from Venice to Gerona with Ryanair!!!) and am now searching for a good rental car deal.

Ryanair is offering a deal with Hertz that comes to about 17 euros per day for a compact. This is less than half the cost of everyone else - the next best deal being CarJet at about 36 euros per day. (Prices include taxes, fees, insurance - the basic works.)

Is it me, or is this just too good to be true? Should I avoid Hertz/Ryanair on this? Does anyone have any experience renting a car with Hertz/Ryanair in Spain? I know you can get unbelievable deals with Ryanair on flights, but I've heard nothing about rental cars. I've read all the comments on CarJet and it sounds like an excellent outfit. Any advice?
