Porschefan,
I really like your line of thought ... 'Loch Ness Boxster', but am surprised that you didn't also go for the 'Monster Aerokit' (option code 666 - of course):
I will be the first to admit that it doesn't do much for the handling but it certainly clears the road, as an additional bonus it is capable of scaring small children within 100yds. Servicing costs are high, Monster has to be well fed otherwise he gets the hump!
Seriously, I was concerned that the operation of my top was incorrect, or, a sensor / switch was faulty, but, it now appears this is standard functionality and the windows are not supposed to close after the top has been dropped.
Great forum, great people, great car.
