Buying a new car doesn't mean you can afford it.
According to a study released Wednesday by bankrate.com, a median-income household can only afford the average-priced new car in just one of the 25 largest U.S. cities -- Washington, D.C.
Bankrate considered three key factors when purchasing a car. They are commonly referred to as the 20/4/10 rule.
The rule is a 20 percent down payment, financing lasting no longer than four years, and principal interest and insurance not exceeding 10 percent of a household's gross income.
The top five metros for car affordability are:
1. Washington, D.C.
2. San Francisco
5. Minneapolis/St. Paul
The five worst are:
25. Miami/Fort Lauderdale/West Palm Beach
21. San Antonio
