I realize this thread has aged , but the solution is very simple if you lease the vehicle .
Example : $400 lease payment + $90 insurance + $25 electricity + $25 gasoline + $40 car washing and maintenance = $580 or a right off of $6960 .
This equals 12,500 miles @ $0.555 and it doesn't matter how few miles you drive .
