How much would maintenance cost on a 2003 mitsubishi lancer oz rally?

I have to do a budget analysis for my math class and it is asking me how much would maintenance be for a year on your transportation. I am planning on buying a used 2003 mitsubishi lancer oz rally in the future so on average, how much would maintenance cost?|||Are you going to do the maintenance yourself or by the mitsu dealer? It's a lot cheaper to DIY than by the dealer. It depends on how often you use the car. A maintenance is required when a specific mileage is reached. So, go to any Mitsubishi dealer's service dept. and check out the maintenance cost for each specific mileage.
