Not that it's a bad question, but personally I don't see buying a Sports car as an equation. If you love the car, no reasonable amount of maintenance cost is going to be too much. It's a left-brain, not a right-brain decision.

Plus, there are so many variables, it's hard to define a number for each individual. What condition is the car in to begin with? How fanatical are you in seeing the maintenance done on-time and what quality level of car do you want? How many miles will it be driven? How will it be driven? Stored indoors or outside? etc. All these things determine the annual cost and are different for every person.

It's a Sports car. It won't cost you Ferrari money, but it won't cost you Honda money either. No Porsche is cheap to keep.

Cheers!
