ya, the bidding slowed down real fast when it wouldnt move

CC Rider was it an Auto Trans car?
Had a '77 Pontiac T/A do that to me once.One of the Valve body bolts came loose,and dropped down inside the pan,preventing the internal Shifter mechanism from moving any further..The trans was stuck in PARK and wouldn't move.
I had to remove the TH400 pan to see what was what.
Easy fix..Hope the Buyer got the car for a song.. :)

Sold for $125,000 and it took 9-10 personnel to push it off the block on the wheel dolly’s

It was an automatic. I think it was repaired after selling.

My buddy drew that car. The consignor told him he would drive it as there were "issues".

Yup. I spy the project manager standing at the driver's side.

Wasn't that the GNX with 568 miles on it? I don't think it was just a regular GN
