To give you a sense of how rare the Grand National is, here’s a breakdown of those production numbers by model year:
The rarest Grand National is the special edition GNX with only 547 units made in 1987. If you want to get your hands on this special edition beast of a car, it’ll cost a pretty penny–usually selling somewhere between $80,000 and $150,000 depending on the mileage and condition of the vehicle.
However, you can find Buick Grand Nationals from the higher production years for much less: between $15,500 to $35,700 for a Grand National in excellent condition.
