From a strictly financial standpoint one needs to compare their current mpg with the guesstimate of 10% improvement. in 10,000 miles from 50old to 55new mpg you would save $73 dollars at $4 per gallon gas used.

in 10,000 miles from 30mpg to 33mpg you would save $120.

These figures are without the cost of charging deducted from the annual savings as that is a continual annual cost, and not an up front cost of say the batteries, charger, wire, switches, ect.

SO MANY VARIABLES..............
