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