Putting in the molded carpet is a serious pain in the ass. There's a shitload of holes to cut, just right, or you'll end up with something that doesn't fit properly - which may happen anyway, my buddy's Lincoln carpet was 4 inches short on the molded width.
I'm wondering if the slightly pricier options are any better.
I'd order it without the sewn on protective pad under the clutch / brake / gas pedals, too. Damn thing is annoying as hell, slick when wet, and your heel gets caught on the edge while driving. It's nowhere near as nice as the stock one. If I were doing it again, I'd just use a floor mat.
