Alright, got curious, did out the math.
Truck: $300/year reg, $900/year insurance, I rounded the numbers. I plan on less than 10k/year but let's call it that, so 12c/m. Gas is $3.60/gallon and I get 19 year round, so 18.9c/m. Depreciation, I bought to own for 10 years, and at 10k/year I will rack up 100kmiles; bought with 73k so at 173k on the clock it will be worth... less. $22k to buy so 22c/m. Don't know about repairs and maintance other than I hope not. Call it 5, as the Jetta (in prior analysis of actual data which I don't feel like digging up) did. 55.9c/m.
Jetta: $300/year reg, $900/year insurance. I really need to drop collision. Diesel is $4/gallon and lifetime average is 46, so 8.7c/m. I bought for $26k and it's worthless now at near 300k, so call it 8.7c/m for depreciation. 5c/m repair/maintance. 28.4c/m.
$2/day in tolls. I don't know why people are including lunch costs, that's not even automotive related. Or do that many people really walk home for lunch? PB&J is awefully cheap; wish I was too.
$52.31 or $27.56.
