Can a finance company legally repossess your vehicle for interst owed even if you have made all of your contractural payments?

Although I am not a professional of any sort when it comes to financial issues I can say that when you purchase a large ticket item such as a car you are usually given a monthly payment if the car is financed through a bank or any other lending option. When you sign all your paperwork they explain to the buyer what the interest rate will be on the loan amount at the time of purchase. I am not sure I have heard of a car buying option where the payment for the principal balance of the loan is made separate from the interest but if that is the case I think they have every legal right to take the car back if you are not holding up your end of the bargain. Although you did make all of your contractual payments, interest is indeed part of the contract you signed when purchasing the car. Banks do not usually give loans for free. They are offering you a service when they lend you a large amount of money to purchase a car or a home and in return you are required by law to pay the pre agreed fees. Until the loan is paid in full including interest the car is not legally yours and they will not release the pink slip until it is paid in full.
