I purchased the Audi front and rear rubber mats for my S-Line and I can confirm they are good quality mats and fit perfectly, they do not give off a strong rubber smell either like some I have purchased in the past, what I like about them is they catch all the water from your feet in the deep segments of the mat and have a large Q5 logo on them. I my view they were well worth the money.
I also purchased the Audi mats. They use the same fitting lugs as the carpet mats and therefore stay in place. The large recesses catch water and mud well. Something I need with a daughter that rides horses!!
