I have just booked a Daihatsu with Interent via Argus from Reus for 80 Euro  8 days. I have had this car out before its not great but the Daihatsu,s are new and I do not do much driving. Take full petrol leave back empty. Also Europa/Interrent at Reus are very aggressive in trying to sell you the optional roadside breakdown insurance, 5E a day you also need to tick it off on the Argus site if you do not want it
