i didn't read through all 3 pages so forgive me if i'm repeating anything.
2008 Ford Ranger V6 4.0L
using CAA's car cost calculator... (which, like anything else, isn't 100%)
but here's some information i've come up with.
round trip communite = 65km
65km x 5 days = 325km
325km x 52 weeks (sure this doesn't count vacation time).
that's 16,900km (potentially, only commuting to work)
now assuming the Ranger isn't a 4x4 - consumption is subjective but you can ball park annual fuel cost with these numbers to be about $2,585
now if you do have the 4x4, increase in consumption equal to $2,936
these numbers are only using 16,900kms with the price of gas at $1.25 and factoring average fuel economy ratings for this vehicle.
