This TA appears to be in great mechanical condition and the original Pontiac 400 engine is still in the car with matching numbers. The stock exhaust is original and factory correct under this TA, and the original cat still remains in place. The muffler has the correct original GM stamp and markings. We have driven this car a few times and it performs well, it does not run hot, it rides tight, and is always a joy to drive. In the video one can observe this car running and driving with no excessive rattles or noises, and the car handles and performs well. This TA is a nice driver that feels good on the road and at highway speeds.
