Personally Im against loans. That too, investing too little from your pocket and getting a high value loan, unless you want to do it for tax purposes and if you are sure that you will be able to replay the loan properly, meaning your income source is not turbulant.
There are a lot of lenders who offer auto loans around the world, and the trick is to find out who is giving the best deal. You need to spend a good time in comparision of all the service providers who offer loans for financing your vehicle purchase. You need to check out the installment amounts, the tenure, the annual interest that you are bing charged, the total money that you are paying the lender throughout the term of the loan, forclosure policiy, non payment of due charges etc.
If you are doing it offline, communicating with the agents directly, they will misguide you completely and give you all sorts of wrong information, make you sign the papers and ditch you. Otherwise, you will have to go thru their multi paged agreement, one by one for all of them, and then arrive on a decision on which one to choose.
Alternatively, you can do that on the internet. There are a lot of websites that list the available lenders who are willing to finance your automobile, with customer reviews and their own impartial views on the lender. This should save you a lot of time, an dyou will be in a community of other buyers and if you get into trouble later, atleast you will be able to be in a group rather than being left alone.
