I'm not trying to state the obvious, especially if I'm incorrect but,

assuming gas sells for $4.00 a gal. (not currently I know, but it was and may do so again) and you have a vehicle that gets 25 mpg (again slightly higher mpg rating that most vehicles) the cost per mile would be $0.16, Now with a scooter rating 65 mpg the cost per mile would be $0.06(rounded). a net savings of $.10 per mile. So If I substitute my scooter for 2/3 of my miles (12k annual) I could save $800.00.

I've always been told if it sounds too good to be true, it probably is? could this be the case. Am I calculating this wrong?

Thanks
