99 Eldo annual expenses?

I just ran across a 99 Eldorado with 66k miles on it and it's going for about 6 grand. It's the classic one owner dream, old guy that follows the maintenance schedule whether he needs to or not. I was looking for a practical 10 thousand dollar car with low maintenance and repair costs. A 99 eldo is clearly a large step in the opposite direction. I'm not mechanically inclined, so what do you regularly spend each year maintaining and repairing your Cadi?
I've always wanted a late 90's eldo, but could never afford one. Now that I have the money I'm not sure if I can afford to maintain it.
