<prompt> Human: So back in 2012 , my parents decided to purchase a 2007 Ford Expedition with 87,000 miles on it . At that time , they were researching the web and found it in Houston and the price was 15,000 USD. However , as Im looking over my parents contract , some things dont make sense . I was looking at the Gap Waiver page and an Agreement to Purchase page and this is what I got ;Agreement to Purchase Page s :21,377.11 - Sales price w access,1,336.07 - Sales Tax,286.81 - Fees Dealer Inv. Tax , inspec. title fee and etc ,22,999.99 - Net Balance,2,600 - Extended Service Agreement ??,3,000 Cash down,Balance Due : 22,599.99Gap Waiver page is what stands out23,188.99 - Amount Financed,13.90 APR,Term of GAP - 72 months,MSRP - 21,377.11 ,Monthly payment - 476.59,Charge for Gap Waiver - 589,At first , my parents were paying 450month for the note , which was told by the car salesman . As time progressed , the note eventually went up to 525 , sometimes 550 . And yes , they are still paying for it because of sudden events that put them behind. Did my parents get screwed over?Assistant: You parents screwed themselves over by accepting those purchase conditions.Human: They were there all day and just signed whatever was in front of them . You right though  <response>: Take that as a rough lesson. Never just signed what is put in front of you. Ever. If you dont understand it, ask more questions.
