Yours has double glazing, also know as heat refective glass.
It's not double glazing as like a S class or 7 series for sound reduction, but it has second layer of heat reflective material bonded to it. It looks like normal glass but has a strange silver/green tint to it in certain light.
I had the colour info, but can't find it at the moment but if I remember right - black & silver made up most of the UK colours. (Approx 20 or so of each)
The rarer colours were sprint blue, mugello blue, Daytona grey and red which made up the rest
There's two LHD cars I found which had bespoke paint and interior. I think the 999 or 998 was a dark petrol blue colour with a reddish dark tan interior - I've got a picture somewhere.
62 or 71 are the two numbers I've heard from different sources (I've havnt got my friend to check every chassis to confirm, but originally 100 RHD and 899 LHD were allocated by Audi - RHD = 80 to UK & NI and 20 to other RHD countries but the full amount was never allocated due to production being stopped before all were sold
The number that were got from the production line never showed whether they were RHD or LHD so I've had to manually check many numbers
Fantastic info here thanks!
Its interesting to know how many were produced and what the various specs were albeit Im not sure at this age it helps with any residuals to much:( Ive dug out a couple of older photos of mine.... reflective/ double glazing or just normal glass ? What do you think?
