Banks and car dealerships often provide car loan options tailor-made for paying off the cost of your vehicle. Most car dealers have their own in-house financing schemes. Some people take out car loans to finance their car, which are actually a variation of personal loans, structured to factor in the depreciation of a car's value over time.
Car loans often require you to make a sizable down payment earlier in the term. The bigger your deposit, the lower your monthly payments will be. Personal loans, meanwhile, can be either secured or unsecured: the former is backed by assets you already own for the lender's security, while the latter is determined solely on the basis of your credit status.
If you choose to apply for a personal loan, lenders are likely look into your credit score rating. This is to ensure them that you have the ability to make your payments on time. Should you have a less-than-ideal credit score, you will have better chances in getting a car loan than you would a personal loan. Either way, poor credit means you get saddled with a much higher interest rate. Ideally you should settle as much of your outstanding credit debt as you can before you begin applying for any kind of loans.
