Yes, that is a car already in my list and has been first mentioned here in post #3085272.
Nonetheless, your post was relevant to me, as new/uptodate informations on this car are given plus quite a lot of photos and even a video, if one follows the auctions link you provided.
I agree with @IROC78, that the informations in the auction were quite a bit scarce to make a purchase-decision.
Obviously, this car has seen some day-2-mods, but I see positively that it reached quite a high price though: auction ended at around 57k plus 1k premium...all US-Dollars $, though both the auction and location of the car are in Canada.
That is the same price-range, the triple-black 4spd Hemi-GTX (driver condition, might have seen body damage on rear driver-side earlier in its life) reached, that was offered on BAT not so long ago (early this year or late last year). That this RL21H6 reached the same price-range is good to see...seems like these cars get some love now.
Too bad for me personally, that I could not take part in the auction, as I do not get notifications about new posts by moparts.org, so I have just discovered this lately. But at 58k$ it is a well payed car for what the photos/vid show me...IMHO.
