Checks will soon be in the mail for customers who purchased cars from a Marshall County dealership between Nov. 1, 2010 and Nov. 1, 2012. Auto Park of Plymouth has reached a settlement with the state over excessive paperwork charges during that two year period. State officials say the dealership was charging customers exorbitant documentation preparation fees. The settlement follows a joint investigation by the attorney general’s office and secretary of state’s office prompted by a customer questioning the charge, called a doc fee. Investigators looked into the costs and found them to be excessive on about 38,000 transactions. Indiana law requires doc fees to be disclosed, negotiated, reflective of actual expenses and noted on the purchase agreement. Customers who were charged a document preparation fee of $228 will each receive a refund of $34 from Auto Park. The dealership will send checks directly to eligible customers.
