So you sold for $5500, a $570 profit. That's pretty good! Saving the oil change, these are all things that a resto would take (Cragars notwithstanding).
Were it not for the appreciation in the car, you'd have almost certainly lost money, but to prove the OP's point, it'd be hard to spend $569 dollars on a resto and still turn a profit.

Really, driving a car for ANY length of time and selling and turning a profit is pretty good, and you've done well for yourself with this one. It's not often a car pays you to drive it!
