I was noodling around in my head last night, and had a brainwave: How many of these are going to be out there?
There were about 130K Colorados produced in 2019. About 10% were ZR2s for 13K. That seems a little high compared to what I've seen in the wild, but they're still pretty new, so maybe not. At any rate, Bison production was limited to 2K. The diesel take rate among all Colorados was 7.4%. The diesel take rate among Canyons was 9.8%; that indicates a higher take rate at the upper end of the spectrum. If we assume production numbers stay steady (they're likely to rise, but by an unknown delta), and round up the diesel take rate among Bisons for simplicity's sake to 10%, that means there should be around 200 diesel Bisons produced. 1/200 is a fairly rare bird among production automobiles... Of course, at the end of the day it's a Chevy Colorado, so absolutely nothing about it is really capital-R "Rare"... It's kinda like saying (anything VW Beetle related) is rare at a swap meet. The gullible will ooh and ah, and those in the know will roll their eyes. Still. If there's any truck going to have staying power, retained resale value, and possibly even reach collector car status, this seems like it. Definitely can't say that about any of the other options... The Tacoma TRD Pro probably comes closest with production in the low 4-digits, but without any meaningful options (things like color or audio systems don't count), there's not a ton of drilling down that can be done. Jeep's Rubicon take rate seems to be pretty high as a percentage of overall production, and even the Launch Edition models were produced in the thousands.... It's a minutia of trivia, but conversation worthy in some circles all the same.
