ditto this, my 2016 rollback also came without floor mats, I tried ordering mats from various gm parts sites, but they were for the ICE spark, which wouldn't line up.
a PN for the OE Spark EV floor mat doesn't seem to exist.
I picked up a rollback/unwind 2016 Spark EV (875mi) a couple weeks ago, and it only came with 1 key :-/
Having only a single key is a recipe for disaster, so I promptly ordered PN 94543206 (my original key is 94543205...) and had it cut at a locksmith yesterday.
Anyhow, the manual for 2016...
