On my 05 TDI it costs me .41 cents per km to operate it. Which factors in insurance, fuel, maintenance, depreciation, etc. etc.
I drive roughly 18 000kms per year.
Total cost = 7380.
There have been no major repairs, I do all the maintenance myself, buy parts at wholesale, get a good insurance rate through my association, and get better fuel economy and generally pay less for fuel then an equivalent gas powered car. And it still works out to over 600 dollars a month to own and operate it.
If I could live close enough to my work to walk or have transit get me there in a reasonable amount of time and there were enough amenities close by I would have a tough time justifying the cost of car ownership.
You start with a bag full of luck and an empty bag of experience. The trick is to fill the bag of experience before you empty the bag of luck.
