A new report the American Automobile Association (AAA) says that the average car costs $9,000 a year to own and run. The AAA said that average, the cost driving 23,000 km a year rose two per cent last year. This cost includes fuel, maintenance, insurance and repairs. The report says the biggest increase costs was maintaining the car – things like oil changes, new air filters, and safety inspections. AAA manager Michael Calkins said: "As a vehicle gets older, you tend to encounter more significant repair costs." The second largest increase was insurance. Americans pay an average $1,029 a year to insure their car. The AAA's report noted that the cost owning a car depended its size. Owners small cars would probably spend $7,000 a year to keep their car running, while 4WD owners would have to pay $12,000 a year their gas guzzlers. Mr Calkins also said that people were keeping their car a longer time before buying a new one. "The length time people keep cars has been going for the past several years," he said. This is probably because the global recession. People are putting buying such an expensive item the economy improves. Calkins added: "The average age the vehicle on the road now is 11.1 years.…The quality the cars is also improving."
