<prompt> Human: I have a 2012 GMC Sierra Standard Cab. It has 30k miles. 4.8 V8 and all the options plus Led light bar 33s and 18in KMC wheels. I pay 438 a month. Only 30 done and I still Ive about 17,500 left to pay. KBB says only about 18,500-19,000 and it doesnt even let me check off that it has navigation.  <response>: Sell car, buy 3k beater.
