Paying for a car in cash may be the best bet, but may not be possible. Shopping around for the lowest interest rate is the best bet. Contact several banks, credit unions, and auto manufacturers. You can save thousands of dollars over the lifetime of a car by selecting a model that combines a low purchase price with low financing, insurance, gasoline, maintenance, and repairs. Call at least five dealers for price quotes and let them know you are shopping around.
Sales are final.
Do not lease a car just because you want lower monthly payments. Leasing a car can be very complicated. Before you need repairs, look for a mechanic who is certified and well established. Get a referral for a mechanic who has done good work for someone you know. Find a mechanic who communicates well about repair options and costs.
