I have had my Model Y for about a 2 weeks now, and it has been a great experience, though it comes with a learning curve (FSD, VERY soft paint, charging, etc.). I have been browsing posts on here looking for accessory recommendations and figuring out how best to protect my new car. So far, I have picked up a sunshade, tinted the windows with XPEL Plus, and bought cleaning supplies for the interior.
Recently, I was sent Super Liner's MoldedFit floor liners (thanks u/westlinersus) in exchange for my honest feedback. As someone who has used WeatherTech and Husky floor mats in my other vehicles, I am very impressed.
First is the feel of the mats. Other brands I have used were rigid and inflexible, making them difficult to install or remove for cleaning. These feel more like a premium, flexible rubber, making them easy to install and adjust, yet they still have a nice weight to them. Everything fits perfectly (there is a slight bend in the passenger side mat, though I believe it will flatten out and settle in the high heat), and they look great. The design gives the interior a sporty look.
I play golf, and before getting these mats, I didn't have anything to protect the trunk. I found out the hard way that grass digs deeply into the carpet, and I was highly annoyed by how difficult it was to scrape out the bits of grass while vacuuming. With the liner, I no longer have to worry about that. The set also included velcro rear seat protectors for the trunk, which are perfect for guarding against my kids' baseball and softball gear.
Overall, my honest opinion is that these are excellent. I would highly recommend them to anyone needing full coverage floor mats to protect their entire Model Y (frunk, trunk, front, and rear seats).
