This is a case of "let's throw on a cheap Earl Scheib paint job and triple the price". That color was never offered in 1972 and you can see they didn't mask anything...look at the front wheel wells! That paint may last 6 months and who knows what sin's it is hiding.
Good (actually bad) luck with the most recent price. http://www.ebay.com/itm/1972-Chevrolet-Impala-Wagon-/272640650658?_trksid=p2141725.m3641.l6368
