I found the standard mats on both my Mk6 and Mk7 GTD pretty good. However, I got the dealer to throw in the "luxury" mats for free. I don't think they are of any better quality, but the white "Golf" lettering and edging looks pretty cool with the white ambient lighting and leather. If I had a GTI, I wouldn't bother unless they did some with red lettering and edging ( I am sure that they don't). Having said that, I don't think I would bother if I had the cloth seats as it would look a bit busy. In summary I would say GTD - go for it, GTI - don't, even if they are free.
