I have used WeatherTech mats for my cars for years to protect the interior from the dirt that is inevitable here in Vermont (lotsa dirt roads and wet weather). This is my first experience with the liners and they seem perfect for my Porsche. The color is a close match to the tan interior. The sides are high so little or nothing can get underneath them, unlike the mats. Although not as deep and thick as the mats, they seem to be tough enough to endure years of use. Installation was a snap. Highly recommended!
