The AppBiz carpet set is beatiful, and seems to be cut very closely to the original, as you can see in the pics. Some trimming will be required on a couple of pieces, as expected, but overall, it looks to be fantastic.
Here you can see the original 24 year old carpet laid out on the garage floor in the pattern it was in the car.
There are some unexposed areas of the original Sliverknit carpet that were untouched, and are as new. Those areas are IDENTICAL in look, feel, and weight to the new Appbiz Sliveknit- they're a truly perfect match.
Removing the carpet from the back of the rear seat backs, you're looking at wood! Yep, the best bavarian black forest wood, LOL! Maybe it's just me, but it's kind of funny to find wood used in a 911 as late as 1987.
