hehe depends on how you spend it.  Here's how to own your personal transport cheaper than taking buses.
buy a cheap 2nd hand small bike (scooter) $800, take the longest available loan, 6years, with interests I work out to 
~$14 per month for intsallments, :bsmilie: if anyone wants to loan you for that meagre amount.  On side note, my friend's Super4 sold for $800 as well. 
 
 
Season Parking 
$17/mth, Most other places either 65c whole day coupon or free.
petrol ~50-70 (take 
$65/mth, I use only like $30/mth)
road tax <200cc $200 = 
$16.7 /mth
insurance depending on age but cheapest around is $200+ (
$17/mth)for small scooters.
maintanance, normal engine oil change every 3 months + general servicing ~$50 (
$16.7/mth)
total per month ~$150/mth, in current day term. :bsmilie:  During my poly days, my monthly transport expenses mount up to over $200 every month (for costs of transport >10yrs ago).
There you have it. Owning personal transport on a shoestring 

 (Hope I did my maths right)
I'm comparing apples with apples, cheapest personal transport with cheapest public transport.  I would compare cars to taxis.
