Plus, if you're spending $135.68 a month in gas, that works out to be 8.48 gallons per week, which is 279.84 miles per week (at 33 miles per gallon). 279.84 miles a week, over the course of a full year, comes out to 14,551.68 miles per year. Over the life of a three year lease, that's a total of 7,655 miles over your lease agreement (assuming you even get 12k miles/year). At 15 cents per mile, that means you would owe an additional $1148.25 when you turn in the vehicle. If yoiur lease is longer than three years, this gets even worse. I believe to get a lease payment that low, they only give you 10k miles/year, but I could be wrong. Either way, I'll just keep driving my Yukon...
Besides, I get 16 MPG, not 14. And almost 20 on the highway.
