hc is correct; but reading the initial post, I assume that it's a car finance company.
If, like hc points out, you'd taken a loan out, from a bank for example and then used this money to purchase the car - then the car would be owned by you and you'd owe the money to the bank.
If you have got he car through a finance company, don't be confused by the fact that your name is on the log sheet .... I'm sure it says somewhere on there, that the registered keeper is not necessarily the legal owner of the vehicle.
