The differences:
Chrome bumpers
Chrome side mirror top, and some pictures show the underneath as chrome too - ours are all black
Silver plastic interior
Bonnet vents appear to be chrome
Chrome or body-coloured windscreen washers
Smaller windscreen wiper mechanism
Smaller grille (although I believe some of the early CC's have the same grille)
The top anchors for the front seatbelts are mounted MUCH nicer than the actual production car turned out with
Solid headrests
Third brakelight integrated into the boot ribs - I love that idea!!!
The rear bumper seems to sit higher off the ground, especially from side-on
Headlights have a blue tint
No aerial
The rear foglight sits on a deeper line in the rear bumper
Clear/bluish window tint, rather than the green in standard cars today
The black plastic that surrounds our side mirrors today was body-coloured door metal, leaving just a small black plastic triangle above the side mirror
The wheels are bigger
The roof join above the rear window is further forward, so that it lines up with the black window seal between the two windows. Our cars today have a longer roof panel and a more steeply inclined rear window owing to this join being set further back to increase the rear headroom (could you imagine having LESS headroom back there???) and also to rectify some of the roof's folding issues
Can anyone spot any more?
The red on the mirrors and red rollover bars may just be one of the fit-out options but the prototype vehicle that was on display 12 years ago featured them anyway. Lots of chrome in the interior but this again may have just been an option
And now, here it is:



This is the interior - nice and shiny!


This rear shot shows the clear difference between it's third brakelight, and the one our cars ended up with
