I don't think the general principals are different for a Boxster, then any other car. If a car is driven for short hops, Porsche assumes that the car doesn't really get a chance to get up to, then operate at normal running temperatures, so I would classify a short hop as one, where the car doesn't get a chance to get the engine warmed and lubed. Although the Boxster is quick to the 175 degree mark, I think we can agree that that mark on the thermostat is a general 'everything is OK, nothing is getting too hot' indicator then it is a proper thermostat. Obviously it's also highly dependent on your climate. Under the above scenario a short hop in February in North Dakota is different than a short hop in San Diego in February.

I would disagree with the previous post regarding engine speeds and the highway. I think Porsche would prefer to see highway usage during break-in, but with varied engine revs, e.g.

3000 RPMs in 5th @75 mph
3800 RPMs in 4th @ 75 mph
4200 RPM in 3rd @ 65 mph
2500 RPMs in 5th @65 mph

That sort of thing.
