1. Drive your car longer. The easiest way to save money on your vehicle is to simply drive it longer, and with the current economic climate, more Americans have been doing exactly that. In 2005, a survey by AutoPacific of 32,000 consumers found that 46 percent of respondents would not be shopping for a new vehicle in the next four years. This year, that number has risen to 59 percent.

Many consumers typically replace a vehicle every three to five years, but today's vehicles are built to last longer, and some manufacturers offer up to 10-year warranties. According to Edmunds.com, the average monthly payment on a new vehicle is $479. Considering your existing car is trouble-free, saving that $479 per month means an annual savings of $5,748 by postponing the purchase of a new vehicle.

2. Reassess your insurance needs. Adjusting the insurance you're carrying can dramatically reduce the amount of insurance premiums you pay. According to Bob Sullivan at MSNBC.com's The Red Tape Chronicles, raising the deductible from $200 to $1,000 on a comprehensive insurance policy will save an average of 40 percent or $100 per year on the comprehensive portion. Those with older cars may want to consider dropping their comprehensive and collision coverage also. Consumer Reports recommends dropping the coverage if the annual auto insurance premiums are 10 percent or more of the book value of the vehicle.

3. Skip the accessories at the dealer and buy after-market products. From sound systems and alarms to wheels and roof racks, auto manufacturers offer a variety of accessories and upgrades for new cars. Dealers often tack substantial markups on their accessories and consumers can usually save up to 50 percent or more by buying after-market accessories on their own. For a 2009 Honda CR-V LX, a portable NAVI navigation system from the dealer adds a whopping $710 to the bill while a similar after-market product can be had for less than $300.

4. Buy pre-owned cars. The old saying that a car loses a large chunk of its value once it drives off the lot is true. When you purchase a brand new car, you pay the retail price, but as soon as it leaves the lot, the car is only worth the wholesale price, the amount the dealer would pay if you were to sell it back to them. In many cases, that difference is up to 20 percent and on average, a vehicle typically loses 15 to 20 percent of its value each year. Buying a pre-owned vehicle can save thousands of dollars by letting someone else take that initial depreciation hit. Many manufacturers also have "certified pre-owned" programs that take the risk out of some used cars by offering extended warranties and putting the vehicles through rigid certification tests.

5. Buy what you can afford. Buying more car than one can afford is perhaps one of the biggest ways that consumers waste money on their vehicles. Conspicuous consumption often leads many to drive fancy cars at the expense of savings, retirement funding and debt management. Experts typically recommend not spending more than 20 percent of after-tax household income on all vehicles in the household. So an adult with a take-home pay of $50,000 per year should spend no more than $10,000 per year for car payments, insurance, gas and maintenance. If you calculate that each year you will spend $1,804 for insurance, the average national insurance premium according to the CarInsurance.com Premium Index, and $3,000 for fuel and maintenance ($250 per month), your total annual car expenses would be $4,804. That would leave you only $5,196 of the original $10,000 limit for car loan payments -- or $433 a month. Bankrate's auto loan calculator shows a monthly payment of $433 a month for 48 months at a current auto loan rate of 7.25 percent equates to a loan amount of $17,994.
