I started with a cheaper carpet kit many years ago, and have forgotten who I got it from. With the first kit, the color easily faded.
Second kit, I got from
www.stockinteriors.com and got the Mass backing option. Being that my burb has a lot of interior noise, I wanted every bit of sound proofing I could get.
Very happy with the color being good to stand up to the hot sun, and the fit was very good. Only gripe I have is that the back edge on the middle section is not hemmed, so you see an un hemmed section at the base of the step up into the cargo area.
Over all, I recommend this kit to everyone even with the section not being hemmed. I guess if it bothered me enough, I could take that section to a shop to get it hemmed up nice.
