I have 2 cars with L B floor carpets, the older one is over 30 years old and just starting to wear. The second is 5 years old and started piling the day I installed it. The newer one looks great, just a pain in the neck vacuuming all the time.
Most people I talk to, swear by "not at" LeBaron Bonney interiors. It's what I have in my town sedan and I love it. Still looks great even after 19 or 20 years.
