i spend around 40-50 bucks a week on fuel going to Uni, out with mates, cruising etc..
servicing once every 4-6 weeks (depending on how much i drive) which is under 100 for a regular (oil+oil filter and sometimes top up someother fluids) and around 300 with brake pads, sparks, etc etc..
insurance is 3600 a year but i dont owe anything on the car so thats around 600 bucks including insurance a month
oh yeah but thats without mods
