Let's see. I drove my Sprinter for 260k. I get consistently 25 miles/gallon of diesel. After some calculations that I will not bore you with, I saved 7000 gallons of fuel over someone that gets 15 miles/gallon on a gas van. If you consider diesel at only $2 a gallon, I saved $14000 so far. I know that gas is cheaper, so let's drop that to $10000. So, I paid 29500 for my van new, so with the fuel savings so far it is as if I would have bought it for $20000. If you can buy a new ford van for 20000, than we are even, but my savings keep adding up. Note that for a while fuel was over $4 a gallon, so, in reality, my savings are a lot more than this.
So, I will buy a diesel sprinter over any gas van any time. By the way, gas sprinters are already here, just that not many people are buying them. However, this is not the time to get into expediting. My van is paid off, which is good, but this year I havent grossed over $500 a week. And from these I pay fuel, insurance, fees... I don't know how I would have made it now with a truck payment.
