Need to see the rear suspension to know if it is likely a true GNX. Right now I'm with the rest of you, I question if it is a GNX. I strongly suspect the seller saw the seats and said "Awesome, it's a GNX!"
Looks like a GN somebody started to do a custom build in the mid '90s and bailed....could a GNX come with T-tops?
The guy who told me about it asked me what I thought it was worth and I told him six grand at the most. Standard Grand National wheels/center caps and other parts you can see in the pictures makes me lean heavily toward standard Grand National
Me too, Darren. No wheel flares either. Driver GNs are out there for low teens. This thing is a parts car or a $3000 resto project.
