How can petrol cost $30 a month if you only travel 35 km in 3 years?

Its an average, sometimes we go months without touching the car, some months we use it every day.

As for the 35000km in the last 3 years, that's an estimate.

It may very well be 30k or 40k and as for petrol, we used to drive a lot the first year we got the car but since we moved closer to the city, we started using less and less so, for example, during the last 12 months, we only filled the tank maybe 7 or 8 times and its a small tank, probably worth 60 dollars each time.

Again all the numbers I gave are estimates and in the end, the total ownership cost may be off by plus or minus $AUD 1k.

Don't be so pedantic, he obviously meant 35km per month as he already explained he only uses it on weekends or grocery shopping.

He says 35k km over 3 years so nearly 12,000km per year. He claims gas is $360 per year. That would get you about 5,000km in a small car like he describes. He’s obviously understated the gas cost, probably by leaving out the larger than normal costs when taking the longer trips to the beach/wife’s family. $30 (400km) of usage a month driving to the shops/short trips sounds about right.
