I am very concerned about the engine vibration at idle on this car. It is very disconcerting to be sitting in a car with just over 1,000 miles on it and feel the engine vibrate. I called Service and the guy said that the Boxer engines tend to do this due to the alignment of the pistons. A look at the Subaru website says that a characteristic of the Boxster engine is REDUCED engine vibration. I look forward to presenting the Service adviser with this information tomorrow morning. Reliability is a big selling point for Subaru, but I am extremely concerned about mine.
