Just had the same experience with my dealer here in the NW. I saw that you can order the all-weather mats with a new build, but the dealers have no clue how to order them after the fact. GM makes $150B/year and can't figure out how to coordinate an accessory with the release of a car? Sounds minor, but I would prefer to preserve the carpets from the mud, rain and snow.
Agree in principle with geeboss. Never bought the OEM rubber stuff before.
Always waited for the Rubbermaid mats sale at Canadian Tire. (Weathertech are great, but kinda pricey..). Given snowless January there should be a rubbermaid sale soon before my Bolt arrives.
Take out the factory cloth floor mats and put in the rubbermaids cut to size. This is std practice for Cdn with muddy shoes or snowboots for 6 months a year. With the rubbermaids the semi melted ice, residual salt/gravel and crap never spills over onto the cloth underneath. Also the rubbermaids clean up nicely (weather permitting) with any tire cleaner. Use common sense to avoid aka-T unwanted accelerator pedal action.
The weathertech avm mats look pretty good but there really is no ridge at all around it. They do look like they could be cut to fit a lot nicer than your average bargain mat but I'm not too sure how well it would fair ?
