Cost Savings: $650 - $1,000

The average American commutes to work 16 miles each way, and the average car gets under 23 mpg, which equates to about 7 gallons of gas per week to commute. At today's prices — $3.68 per gallon on average, as of this writing — that's about $25.75 a week, or nearly $1,300 a year!

Share your ride and the gas bill with just one friend, then, and you each save $650 a year. Fill the car, and you each save nearly $1,000.

And remember, the average car costs $9,000 to own, if you factor in gas, registration and insurance, maintenance and depreciation and other costs; if you halve or quarter the number of miles you drive, you'll also save on maintenance, and your car will last longer.
