StarCar

the author of this app says:

What goes in a car? Money, mostly! With StarCar, you can keep track of every bit of it. Gas, Oil, Maintenance, Payments, you name it. Of course, all that record keeping doesn't do any good unless you can see the information, too. StarCar can display graphs, a journal, and a summary of the information. You can even Export the information from StarCar, and Import it into Excel!
