Just clicked through to the Costco website, they are advertising Michelin 'EdgeLiner' custom-fit mats on their website: Michelin EdgeLiner Precision Laser-Fit Custom Floor Liners They don't have custom fit for Tesla yet but when you go through their configuration wizard, the Tesla Model S does come up and the wizard asks you to leave your name and email for a 10% off coupon once they have them available for Tesla. The pictures look nice and they can be ordered in black, gray and tan. Look as nice if not better than the Weatherguard mats and seem to be priced lower. Has anyone else seen this product on another car? Suspect that if enough of us express interest they'll move a bit faster to get the Tesla version out.
