2020 SSV from Chicago motors

[CrashTestDummy]

5C1 is some sort of 'plexiglass panel' on the left hand side. I can find no other info on that.

Judging by the lack of a spotlight and the full-length front spoiler, I'd guess it's a standard Tahoe. It does have the steel wheels, but does it have other hints of service, like rubber mats or signs of a second battery? I know these things can be added or deleted options when ordered, but that's what I'd look for.

rubber flooring and no second battery, however there are signs of drilled holes in the headliner and rear plastic where lights have been installed, also in the second battery tray there are holes maybe from a siren speaker. cloth in the front and vinyl second seat with no third row. definitely a utility vehicle. Carfax had it listed as a Tahoe Fleet spending it's life around San Antonio TX. It's looks almost identical to my 2011, except that it has Tahoe badges. It doesn't have the extra 8gage wiring going to the rear as well. So I guess it's just a low end LS. That being said it was a great deal and a fun field trip to Chicago.

It's not an LS when it has steel wheels and rubber floor, there's probably some fleet code to it.
You should try to find another police one with a listed vin to check the codes to see what it shows as and if you are lacking any of the HD parts. It could be this new way of running the rpo codes its just not showing 9C1 or the designation. There's been codes missing on some of the stuff I've looked up.
