Yearly Milage

[achillies]

I know that not driving a car enough miles is not a good thing....I have read that the sweet spot for Porsche mileage is 5-7000/year or so. But what is the point where mileage is too low? I put 3,000 miles on the car last year.....is that too low or OK? I do oil changes each year but I have wondered about the mileage being enough.

Thanks
Bob
