I get frustrated with the boring grey car interiors. I tracked down some blue carpet mats (made in NZ), which brightens the interior substantially without being overpowering. Most people just assume they were standard, but fellow Golf 8 owners have been wowed by them.

I bought blue colour carpet mats from this company. The also sell red, beige, dark grey and black.

I am not trying to sell them, and have no affiliation with the company. I was reminded about them as they sent me an email today, giving 15% off for father's day for orders placed by 5/9/22, using the code THANKSDAD
