I have access to Alldata Repair and Mitchell On Demand. I stopped buying books and 1 car specific manuals along time ago. These programs cover all makes and all models from 1982 until 2014. I have had no issues out of either of them and the repair info of them are what dealerships use and other auto repair facilities as well.
