What are the favorite cars of America's wealthiest families?
If they live in California, put the Toyota Prius hybrid on the list.
Auto-price-information company TrueCar.com compiled a list of the 10 wealthiest ZIP Codes based on Internal Revenue Service data from 1,000 or more 2011 tax returns in each locale, and then looked at the auto registrations in those communities.
"For affluent buyers who live in places where environmental concerns reign supreme, the Toyota Prius is the ultimate status symbol in eco-luxury," said Kristen Andersson, an analyst at TrueCar.com.
The Prius was the most popular vehicle in Century City, which with an average annual income of $751,000 (as reported on the tax returns), ranked fifth on the wealthiest ZIP Code list. It was followed by the Mercedes-Benz E-Class and C-Class sedans. A more pedestrian car, the Volkswagen Jetta, ranked fifth in the community, behind the BMW 328.
