Nalley INFINITI Marietta

Drove in from out of state to purchase a "certified" used car found on the internet. 1) The car was listed as certified, during the financing portion of the purchase, it was quickly passed over as non certified car. We noticed and questioned. We showed Nalley employees 2 different websites that listed the car as certified. We were told if we wanted the car to be certified it would cost us $899. "If we can add $899 to the cost of the car we will sell it as certified" What??? 2) Added an addition $1000 to the total cost of the car for a paint protection and interior protection "we add this to all of the cars we sell, once we had a person buy a car, park it under a tree then sued us so we add this to all of the cars we sell" ??? 3) My son has excellent credit, added extra interest rate due to "first time car buyer"
