Sounds pretty good! Hope I could help a little and that you will enjoy the car!

Did you consider leathered airvents? It might be a bit over the top but haven't this should be about the last plastic piece that is not covered in the interior then. For a convertible I would also consider the leathered sunvisors but if I get it right you order the coupe? I suppose the Porsche dealer can show you some examples - hey, the car isn't cheap so why saving at the wrong place...?

Do you go for the std. leather? I heard that the Natural Leather is much softer but also a bit touchy.

Anyways, you should have quite a lot of fun with the car and I am looking forward to see it on the pictures!
