These are custom made aftermarket mats that have a nice pile to them. They are black with red piping and will only fit a coupe. I have a convertible and bought them as a 4 piece set therefore I am selling. Never used. They DO NOT fit a convertible Maserati.
Years that will fit are 2009-2018 Maserati Gran Turismo Coupe
I found and bought good floor mats on concord-parts.com, their catalog and prices are great. If you need something like this or another spare parts(especially for European cars) I recommend to contact them.
