Original, Impala Convertible! Runs and Drives Great! 327 Engine and Automatic Transmission. I have owned for a year and bought from a party that had owned the car since the early 1980's. The engine runs excellent and believed to be original. The transmission was rebuilt one year ago at a cost of $3,000. The majority of the interior is original. The exterior paint is not original and was repainted ( off the frame ) within the last ten years. New tires put on one year ago. The top is original. Great Car!
