Carpet replacement proven source?

I have a new to me 2000 Buick with a carpet I would like to replace.
Unfortunately I had one replaced on another 94' Park last year and ordered a $115 carpet that advertised well and I was very very disappointed..

The website was extremely well advertised, the carpet I got was very cheap carpet quality. Not really form fitted or rubber backed, the knapp comes off in big clumps still, after a year and sheds badly like a dog. It really wasnt form fitted as advertised.. Its like the carpet was just rolled off and cut and maybe shaped a bit.

Has anyone found a reputable carpet source they have had good results from?

Thanks..
