Congrats on the new Malibu, looks good! Lots of features in that car - enjoy.
The SXM absence is a strange one and the site is a bit misleading (though it is correct in the product brochure which dealers rarely have in stock). It previously said under the build and price "SiriusXM Satellite Radio is standard on nearly all 2016 GM models" when you select the LS. When you list that under a car that doesn't have it that seems a disingenuous. One would think a 23,900 car would be part of the "nearly all" considering a 16,000 Spark has it. The other oddity is the 7" MyLink can have it, they just software disable it on the LS trims because the module isn't installed or connected.
Welcome also.
I like your color. When I was looking over a year ago, I was wanting the turbo, but could not find one with silver or red. Turbos were hard to find in the Denver area. I settled on a 2014 dealer demo in Black Granite w/12k on the clock.
