I am going to change my carpet but have only noticed two manufacturers on websites, ACC or LMC. Has anybody used these, and can you give your opinions on fit, ease of installation and quality? I intend on using the mass backed in the factory Titanium Gray. I guess quickness of installation is a moot point as it will be a winter project and time is not of the essence. Thanks in advance for your input. BTW, do we get a discount from the parts guys that advertise here? I'm almost positive we do.
