If the carpet is good but just dirty or faded a bit I'd go with taking it outside turning it upside down on the cement and dumping the dirt and stuff off of it, (I used a good power washer after flipping it over and it got rid of so much dirt it turned to mud on the driveway" wife was pissed to say the least!")then using a scrubber clean the carpet with resolve carpet cleaner to see what you have. if it's faded a bit you can get SEM cloth/vinyl dye to bring back the color.
If it any way worn through at the heel pad I'd just replace it. (oops just looked no heel pad) your choice. AND you relocating the shifter so the floorpan might show through the carpet...
if you go new, lay it out to relax in the sun for a couple hours before installing. measure,measure,measure. The hotter the better,oh and did I say measure the cuts? use anything to hold into location. I used bricks, lead bars,tool boxes and whatever fit in the odd areas I had for my convertible. I did have to help a couple areas around the hump with a heatgun to fit better but that was because it had cooled down (night time) and I was just plain slow
I got mine at stockinteriors.com for 139.00 plus shipping they are heat molded to your floor pan and a pretty good fit( at least mine was) some need some persuasion to fit tight I did the stock 80/20 loop but could have done any of the others for a slight price increase
