I was considering new carpets a few years ago (but still not done it!!) and got samples from a few suppliers, but not Rimmers as had heard they were not so good. IIRC I had decided on Coverdale, although not from their expensive ranges.https://www.carcarpets.co.uk/triumph-tr ... 5256-p.asp
As far as I know it is not possible to get moulded carpets anymore although there was an Australian company advertising as such a while back. I think it was subsequently found that they may not be and the post cost was prohibitive. I guess I will have to start again when I actually get around to it. Most suppliers will send samples if you ask.
