You’re in the market to buy a new car and that’s great. Today most everyone buying a new vehicle will need some form of auto financing and if you find your personal finances or credit are less than perfect, you can still get a very affordable car financing if you know how.An informed car buyer is a smart car buyer. When you know your auto financing options and you have your car financing set up and approved before you talk to any sales person, you can walk into a car dealership and negotiate a better deal on your terms without feeling intimidated, regardless of your financial situation.If you know that you have certain credit challenges, you should understand the differences between bad credit car loans and guaranteed auto financing.Bad Credit Car Loans…Bad Credit Car Loans typically have been available through new car dealerships on the purchase of a new car or a pre-owned certified used vehicle. The actual auto loan financing paper-work is handled at the dealership but in general, the bad credit car loan finance contract is sold off to another lender. That lender will maintain and service your loan. Loans typically have a term of 24 months up to 60 months. The downsides to a bad credit car loan are that many franchise car dealerships are not set up to arrange these type loans in-house, interest rates and cost can vary widely and limit your auto purchase choices.Guaranteed Auto Financing…Guaranteed Auto Financing differs from a bad credit car loan primarily in that this type financing is offered directly by smaller or independent auto facilities. Your finance contract is provided by the actual auto wholesale dealer and the loan is paid directly to the auto dealer that sold you the car. In other words, you would be financing your car purchase from the company that owns it and sold you the vehicle. Guaranteed auto financing is used for the purchase of used or pre-owned vehicles and not typically for purchasing a brand new car or truck. Loan terms are shorter than more conventional auto loans and they rarely offer terms over 36 months.The big advantage to guaranteed auto financing is that often no credit check is required to obtain this financing. Payments are normally made weekly and sometimes in person. One disadvantage to this type of auto loan is that many car dealers providing guaranteed auto financing will never report your credit to the credit bureaus. So if you’re making payments regularly and establishing an excellent payment history, this will not be reflected in improving your personal credit profile or your credit score.Your best approach would be to start now and see what financing options are available for you. There are excellent specialized auto financing services available online today that offer a whole range of affordable car loan programs even if you’ve been turned down for financing or you have poor credit, bad credit or other financial considerations, you’ll be surprised at how they can help you to buy a new car.You see now that there are major differences between a bad credit car loan and guaranteed auto financing and there are other financing options besides these. Get approved for the best car loan for you first, then walk into the car dealers and negotiate on your terms.
