True,
PDI issues or TSB information can come up when you bring your car in for its initial service.
What I was getting from this service advisor was he was assuming I owned a used Boxster. I firmly reinforced the fact that I bought it new. (people of color and other nationalities can buy a new Porsche too)
Bottom line, he just didn't care to slow down enough to listen and acknowledge what I was saying to him.
As for the balance issue, I'm extremely sensitive to vibrations in a car. My nickname was "silkshorts" when I worked for Chrysler and Mercedes as a NVH tech (noise, vibration, harshness).
The Boxster is extremely smooth, and I'm noticing a slight increase in tire vibration as the tires wear. I have a really noticable steering wheel vibration from 78 - 84 mph even with the tires warm. It just happens to be in the speed range I travel most. I get the typical cold tire flat spots in the morning, but it goes away once I hit the highway for about 5 miles.
