My Porsche 928 Projects:

I have owned my Porsche 928 GTS since April 2000 and have driven it more or less daily since then.

Although I consider it in most respects an absolutely great car - I have added many subtle features/ improvements to the car in the following key areas: driving controls, safety equipment, maintenance features, convenience items, entertainment systems and a few purely cosmetic updates. All these listed projects are completed and are mostly either minor changes in keeping with the car and its evolution or in some cases represent retrofitting the original European features of the car. I also have list of an 'in progress' additional ideas I'm currently working on...

My general approach is to limit visible changes and to use equipment in keeping with the car (often Porsche-OEM original) or improved materials where warranted (Porsche did make some mistakes...). If I change something substantially I will usually implement the changes on an alternate module keeping the original so I can revert back I am also loath to delete or permanently modify any wiring - preferring to leave the original wiring & connectors in place and adding new removable wiring for any new features.

I mostly choose to add features which I consider Porsche would have added (in some form) themselves if the car were further developed beyond about 1992 when the last of the GTS developments ended.
