Just joined a few weeks ago after I purchased my 2012 Prius plug in advanced. Love this car. My 2006 Camry was getting 30 mpg on ago good day and was costing about $275 per month. Now I'm getting 60 to 65 mpg on a regular basis and seems like the fuel bill will be about $120/month. I plug in every night for about 3 hours and use the "EV" electric mode on the roughly 11 miles getting to and off the highway both trips.
