The email I go from weathertech IRT floor mats.
Hello,
Thank you so much for reaching out to us. We do have the option for the Floor Liners for the 2018 Model 3 in development. They are currently in the design stage. There is no specific date for availability. We should have them available for purchase in the coming months. I am going to put in a product request form for you so that you will be notified via e-mail when the liners are available for purchase. Thank you again for your inquiry and please let me know if you have any other questions.
