Here's your cents per kilometre...
Assume 4 decent tyres at $175 each average for a $700 change over, lasting 60,000km = 1.16 cents per k. You're scraping the bottom of the barrel, worry about the last 1/2 cent mate!

Car Rego & Insurance, assume circa $1200 / year minimum, for say 20,000km travelled = 6 cents per k for the privilege of parking your car in the driveway...
Fuel, lets go with 10l/100km at $1.40/l for 20,000km travelled for the year = 14 cents per kilometre...
Now, let's talk depreciation... $35,000 Jap SUV, after 4 years, and 80,000km later, she'd realistically be worth $18,000 max... A cool $17,000 spread over 80,000k's = 21 cents per k.
A BMW, let's go for $90,000 new, after 4 years and 80,000km, assume resale at $55,000 max = $35,000 down the drain or a whopping 44 cents per k !! Just on depreciation....
