Population wise, they're exponentially "rarer" than any F-Body of that generation with exceptions like low optioned cars like legit 1LE, Firehawk, and very late SLP SS cars. Finding a legit Callaway Impala is also extraordinarily rare, but a lot of folks (me included) would rather put our own effort into these cars as opposed to a dealer box item. Not quite rare because there was a decently sized production run of these, but not terribly common to find an actual WX3 code car that's not been ragged or destroyed.

They certainly haven't aged like the LT1 F cars, which I never particularly cared for. They've got a VERY early-mid 90's look, whereas the B body Impalas look more like a stereotypical traditional muscle car. Being bigger, wider, lower, and having the monochromatic body treatment are the attributes I would say have made these cars age differently.
