Car Hire Prices

Hi , Have just registered with EOS so am new to all this !!    Have been hiring cars for the last 3/4 years at various times of the year and from 4/5 different companies and as I'm sure everyone has noticed , the prices are escalating all the time ---- have recent quotes for 21 days in August of around 800 Euro ( I apprecaite it's high season !! )   -- would normally book from Malaga Airport. It's fast getting to the stage of looking to buy a car in Spain but our problem is that our house is in a small village near Antequera and would have to get from the airport to the house each time or leave the car somewhere near Malaga airport.  I was wondering if anyone knows of a reasonably priced long term car park area near the airport or an idea of where to look for a 2/3 year old medium size car .............. Any ideas would be welcome ...........   Regards etc. etc.
