Hey guys. I’m buying a 2013 optima off a friend. Recently her motor seized up out of no where. I’m reading this might be sorta common. She took it to a Kia dealer and they did some work on it and told her she basically got a new motor. The car has 169,000 miles but I’m interested in buying it because of the new motor. I am having a hard time understanding based on the invoice if the motor was actually replaced or not. Mind helping be decipher it? Thanks!
