The Grand National new at the time would have been a sound GM buy from my investment opinion. Keeping it garaged, low miles on it and original. Just responding to a comment. It’s not the review car. Good Luck.

Well the Iron Duke was produced from 1977-1993 and used in US mail trucks, so I would say it was a trusted engine.
