Nice table but it's missing the increased depreciation and added maintenance of the more expensive vehicle.
Insurance on the Accent is about $150 per year, I only carry liability/comprehensive. When I added it to the policy the truck insurance went down (multi-car), so it's actually less than that.
I average 19,000 miles per year on the Accent. It cost $12,500 new + $1000 tax/title so $13,500 in 2008. I don't have every sales receipt for gas that I've run through it but I would guess it averages out to close to $3 per gallon. 191,000/33mpg = 5788 gallons x 3 = $17363 in gas. Truck gets less than 18 mpg these days. 10,611 gallons x 3 = $31,833 minus $17,363 = $14,470 gasoline savings.
Maintenance on the Accent has been very inexpensive. 2 timing belts, 2 wheel bearings, plugs, tires, oil changes, and a couple other minor things. I figure I'm doing far less maintenance on the F150 driving @ about 1000 miles per year so anything I didn't have to spend on the truck because of mileage savings should be subtracted from the car maintenance.
I still think I'm ahead. Even tires are way less expensive.
I completely understand people like to drive trucks. To each their own, it's America after all.
