I got it, and it's not as large or impressive as the same thing on my wife's Audi Q7. I might skip it if I did it over.There's a chance it's different for UK cars but US cars have full exterior visibility LED lighting as standard. So, when dark outside, it lights up all of the handles and the ground around the car. I'd say I'm 95% sure but this might be one to add to the "Ask a dealer" thread.
The logo projector just adds the "Porsche" name without any actual funcionality. I can take a photo later when it's dark.
