 Drive 30K miles a year. Cost for diesel will pay for itself in 1 year. Range 500 miles using 12.5 gallons. Came with 6 months free Satellite. Now do not have to listen to the political hate shows. If American companies had this engine they would need to be bailed out and we do not need to rely as much on foreign oil. Traced in 1999 truck(clunker) getting 12 MPG and now getting 40+ MPG  Great car so far(6500 miles)
