A sticky would be nice. I personally own a copy, but would buy another if it were an ePub or PDF as I use an iPhone & iPad.
I'd also like to point out The Pelican Part 101 Projects web site at:
Porsche Boxster 986 (1997-2004) / 987 (2005-2008) Technical Articles | Pelican Parts
This is particularly useful for someone that is considering, but hasn't purchased, a Boxster yet as it provides a lot of useful information in regard to the basic maintenance of the vehicle and is accessible without a purchase.
