The recent GNX #54 with 148 miles is the same one from a few months ago that "SOLD" at Mecum for $82k with 144 miles.Owner buy back,or did it sell and new owner flipped for a cool $35k profit !!!!!!!The 4 other GNX's at Mecum recent auctions went to "Bid goes on" not selling.
Southern Motors in Mi just sold one with 5k miles,asking $69k,don' know what they got.
As far as paint failing and headliners coming down,UV light and heat speds up the process.I know of a few orig paint GN's/T-types still with no laquer cracking.My 1,400 mile GN still has perfect paint,and no sign whatever of headliner to fall yet.Proper storage is key,the prevous owners of mine state they never rolled windows down to retain that "new" car smell,....and it does.When you open the door,the new car smell hits you very strong.
I follow low mile GN's and GNX's when they come up for sale and it is amazing that some cars with extreme low miles weren't cared for and look like they have triple the amount.
The GNX in topic of this thread with 23k miles,to me,engine bay,does'nt look like one should be only having 23k miles.It is in Florida,so that salt air can be causing the corrosion/rust I see.Florida cars aren't as perfect as everyone thinks.If it were stored outside under a carport,would explain that and maybe the repaint,or one previous owner could'nt stand the shitty factory paint job.
