How much would it cost to maintain (annually) a 1965 Ford Mustang?

I'm planning to purchase a 1965 Mustang. The one I'm looking at is mechanically sound, and in very good overall condition. I will probably drive it 5K-7K miles/yr.
I don't work on vehicles myself so it will have to go to a mechanic for service.

Can anyone give me a rough estimate?
