Alone in mods with the turbo just going on I'd say around $6000 spent over the course of 18 months. Petrol is around $60/week, insurance is $900/year, rego is $450/year, tyres every 12 months, serviced every 5000km's... it would add up to be a fair bit. *shrug* Its my only hobby and my only toy, I dont smoke at all or drink a great deal (so yes I am boring)
