It sounds to me as though you got a good deal! It should last quite a while, and meanwhile you have no car payment! I like that, too. I'd rather drive an older car, even kind of crumby looking, if it gets me around and there's no car payment.
It's so nice to be able to go out, hop in the car, and go wherever I want. I put a grand total of 6 miles on my car most days, if I go out at all. Very low mileage over the year, so I expect the car will last a while.
