No the loan contract is completely different from the installment agreement. The installment agreement has the interest, amount financed and how much interest would be incurred after years of paying the car loan. The loan has the actual sales price of the car with taxes, title and warranty. AT LEAST this is how it's presented to me in two separate documents.You aren't making sense. A "loan installment agreement" is the "loan contract". You could (and should) have read (or, at the very least, skimmed) the thing before you signed it. You know how much you agreed to pay for the car. You had to have known the general terms of your loan agreement (ie: $250/month for 5 years, or whatever).
So, how much did you buy the car for?
The warranty on another note has the actual price of the car, that we originally agreed which is $9000. On the loan agreement (which I didn't see only after the fact) has the price of the car at $13,500.
