It's not often you get to say 'perfect' about almost anything, but this is one of them. The product was a terrific price, it came in a day, was packaged perfectly, was easily removed from clever packaging, it was simple and obvious how to install, and it fir perfectly, both front and back. True OEM fit, feel, and finish. Like I sad, peeerfect for my VW Touareg. As advertised. 5-star. And I ask again, how many 5-star ratings have you given? This is my first and I'm n old guy. Been doing business on Amazon for decades.
