From a marketing stradigy, its a great motivation to buy these cars. However, its a slap in the face to conservationists, EPA, ect. Instead of making cars that get good gas mileage, they come out with this.
FUCK YOU GENERAL MOTORS.
But here is the funny thing and this plays on the dumbasses of the world.
If you buy one of these cars that gets 15mpg and you only always pay 1.99 a gallon...
in 20,000 miles, you use 1333.3 gallons = $2653.33
If you get 40MPG and lets say gas is 3.50 (thats about 70cents higher then the average around here)
in 20,000 you use 500 gallons of gas = $1750
If you get 30MPG at the same price
in 20,000 miles you use 666.6 Gallons of gas = $2333
So to the dumb asses of the world, buy into this, and still pay more at the pump in a year
