Ran across
trimmable liners on Amazon, maybe they'd work if the dimensions are big enough. That link supposedly fits MINI Cooper SE.
I received the liner and have installed it. My thoughts:
THE GOODS
It's plenty wide and long enough to cover the entire hatch and rear seat area.
I like the composition of the rubber. It is about the perfect mix of slippery and tacky.
It was inexpensive ($30).
The guide lines made it easy to trim with a pair of standard scissors.
THE OTHERS
It is too wide for the SE, even trimmed to minimum width, if you want the lipped portion aft, and, if so, the edges of that lipped portion will be bent up a little. Yet, by being a little too wide and bending up, the mat overlays the aft seat belt buckles to keep them quiet and will protect the bottom edges of the bulkheads from scratches.
The rubber is thinner and, therefore, less stiff than I had hoped for. It has the consistency of a thinnish, rubberized, front door mat. It came rolled up in a 3" x 3" square tube box. You can see in the photo that it drapes over the outboard edges of the headrests and sags a little between the two of them.
The rubber has a fairly strong tar/rubber odor, even after sitting unrolled, outside, in the rain all day. (I read reviews complaining about the odor, so I tried to mitigate it.) I'll continue to monitor if it gets less smelly.
THE VERDICT
Overall, I'd give it a 7/10 for use in the SE. It suits my needs and does what it is supposed to do: protect my hatch and provide a smooth surface to slide my clubs in and out. However, it lacks a perfect custom fit, it's a little flimsy, and I'm hopeful the smell will dissipate over time.
