What's the biggest cost of car ownership?

Usually depreciation (what the car loses in value), followed by finance costs, then fuel. For a new car, depreciation can be 40-50% of total cost over 5 years.

How much should I budget for car running costs?

A good estimate is $3,000-$6,000 per year for a typical car (fuel, insurance, rego, servicing). Larger or luxury cars can be $8,000-$12,000+.

Are some cars cheaper to own than others?

Yes, significantly. Small Japanese cars (Corolla, Mazda 3) are among the cheapest to run. Large SUVs, luxury, and performance cars cost much more in fuel, insurance, and servicing.
