So apparently my 2015 Golf S TDI is only worth 16,800 as of Sep 2015 but it is currently worth 15,800 according to NADA. Something doesn’t add up. According to the “Help” Line they have to abide by the third party (NADA) prices and if I don’t agree I can send a letter to the courts. Am I crazy or is NADA lowballing us?
