After constantly being passed on the highway by minivans and dump trucks I thought it was time to test my speedometer. My wife and I drove side by side and we found when the Boxster said 70 MPH, the other vehicle said 64 MPH. Has anyone else ever experienced this problem and/or is this a typical problem with Porsche?
I have only owned the car for about a month and absolutely love it! However, when I feel the need for speed (as is often the case), I would like to accurately know how fast I am going.
