Really, how many Porsche crest do you need on the car? "Yes we know what you drive!"
I'll stick with OEM since I prefer the velcro setup, and I'm tall so I actually prefer the thinner mat (feet lower to the floor) as supposed to the thicker aftermarket mats.
In fact I bought these real thin rubber mats for winter and I've still go them on the driver's side.
