That sounds pretty good to me.
GNX started out as "1 of the Fortunate 547," a number went to select dealers, and also had mark-ups and dealer premium pricing. I remember hearing second hand, that someone on the dealership grapevine would know which dealer still had one & how much etc. My guess is a lot ended up in the hands of buyers who could afford to store, maintain and occasionally drive a Sunday driver instant classic. I know of two here in Dairyland - one 3K & one 8K mile originals that have led very sheltered lives. You know - out in the garage marking its territory in the extra stall.
There are a few rare REAL GNX's that have been restored because they were worth doing. No Dodge Diplomats get put on the rotisserie, so while some GN's of T's get rusty, wrecked & parted, others might slip through to the crusher or "Cash for Clunkers," I believe the GNX would more likely survive.
