Generally I believe that Porsche design is not to be messed with and too much 'customization' devalues the original.
Couldn't resist a couple of tweaks though which have been a success.......
First the DRLs which on eBay are about 5bucks and then the satnav also on eBay for around 60.
Finally throw out the 'cigar lighter' and replace with a 2 socket usb again for a few bucks and charge 2 phones at the same time!
