I remember seeing this Polara on a broker/dealer site soon after is was sold, listed for $9K. I don't believe they did anything to it, and listed it for sale just like they got it.
The dealer that used to be in Lindenhurst, IL was Luedtke Auto Group who had a reputation like a bad rash in the B body world for selling a bunch of Dukes of Hazzard Chargers over the years that were overpriced rust buckets with half the weight of the car being bondo. (Don't take my word for it, check the DodgeCharger forums for lots if comments on them)
I don't know if it was ever sold by them or knew what happened to the Polara until seeing it posted here today.
