The time came...traded my Z last week. I have a
Roadster Trunk Mat left over. Originally came with a 2010 Roadster, then used in my 2013 Roadster as well. The mat is clean, and still looks brand new.
EDIT:
Sold!
To reiterate...this is a trunk mat for a Z Roadster, not a Coupe. The Roadster has a completely different size/shape trunk than the coupe.
