I used these in my 2014 Model S for two years and when I sold the S to get an X in 2016, I kept these to sell. I'm finally getting-around to selling them. They are listed on eBay:
Tesla Logo OEM All Weather Floor Mat Set for Model S (Front and Rear) | eBay
Selling price is $115 with free shipping.
They are genuine Tesla mats with the Tesla logo. Tesla is currently selling these for $245:
