does anybody know how much it´ll cost to drive your own car fom barcelona to granada,avoiding tollroads???

Hello... ummmm.. Mr. Bird. (interesting username... ) Welcome to our message board.

You'll find a route from BCN to Granada absolutely free - except for gas/petrol, that is. Are you asking for an estimated cost for that too? However, by avoiding the toll roads you may spend about the same on gas/petrol, don'tcha know. Plus, it'll take you longer.

Have you checked http://www.ViaMichelin.com yet to see the route? There, they'll show/tell you where the toll roads are.

Good luck on the lonnnnnnnng drive!
