On auto parts

What I need is to own my own auto parts store, especially with a car like mine, that's a 1991, and barely still running. Actually, it does run pretty well, but needs new breaks, makes a strange squealing noise, and leaks coolant so that I have to add some pretty often. Was every week but now I better make it every 5 days at least. I'm always scared something else is going to go wrong with it. If it happens soon, I just don't know what I'll do. I make good money but I have many demands on it.
