Lets assume 15 miles total each day.
years worth of driving to work: 5 days a week, 52 weeks. 260days a year.
3900 miles a year. (I envy you BTW)
Electric Sol:
$8000 investment. No fuel charges.
Dump truck with a big block (5mpg):
$2500 for the turd dump truck. 780 gallons of fuel consumed or $2808 in fuel charges. $5308 total investment.
Moral of the story, you could drive a dump truck to work everyday for a year and save $2692 doing so instead of buying that DelSol.
