expect to fill your gas once a week, gas prices here in vancouver is 89.9, the highest I ever seen in my lifetime.. probably due to the war that is coming.. i spend around $200 canadian dollars on gas per month.. but gas is cheap, maintenace is what kills you.. ie:

air mass sensor $600 (DIY)
oil change $80 (DIY)
brakes $650 (DIY)
sparkplugs $120 (DIY)

etc.. expect to change your brakes and rotors frequently!
prices are all estimates
