|I'll say they're a higher end generic, and definitely not as plush as OEM. The backing is as good as it's going to get. Definitely worth $100 (if it gets to that pricepoint in a few weeks).
I don't know for longevity however as I actually keep the OEM ones I have on top (with the metal hook). I only removed for when I had a hot date and they've held up great that way.
It looked killer with the 300ZX red stitching, but that's obviously not the case anymore. I would have purchased the trunk one now if they actually had it with the same 300ZX red stitching but I won't pay them to advertise for them.
