I have a 2018, so the cargo carpet is shale. Buick switched it to black in 2019 (with shale seats), which is a lot more practical. Trying to keep that acre of carpet and seat backs looking good will be a losing proposition with the dog and hauling stuff. I think the black plaid looks pretty nice too...Do you have light colors carpet in the back or black? I have shale seats but the cargo area is black trimmed. I've seen photos online of cars with shale seats also having the light cargo area. It is pricey but these cargo liners are interesting to me, I'm not typically a pattern guy but the black plaid could be interesting as a change of pace.
