Just factoring in the Total purchase price I paid for my '06 SVM.. 153,000 miles divided by $15,300... = .10 cent's. Not bad at all! Not considering Gas and Maintenance of course, but that has been reasonable as well.
.10 per mile is better than the electric bicycle I built earlier this year, which has just passed a $1 per mile. But thats quickly getting lower since it has no fuel costs. And maintenance is near zero.
