What top speed have you been able to get your Boxster up to on a closed course ? Both of my Boxsters are factory stock. I find getting to top speed takes a little time and distance. My wife I were in the car together both times. The '98 had 130K miles on it at the time and the '00 S had 60K miles on it at the time. We have been able to do it twice so far. Once in the '98 Base at 153 mph and once in the '00 S at 166 mph. Both times the cars had a more to give but due to getting close to the end of the course, we had to get out of it. I think the Base could have hit 155+ and the S 170+ if we had more distance to work it. What can these cars actually do flat out on an open road like the Autobahn ? We need an American Autobahn.
