Yes, Sir, press or show cars were specifically 'prepared' before being released to the show or the 'crowd of motor journalists'.
This does normally include a special engine performance check and so on... and it is indeed kept confidential...
what it is that is done to any specific 'press- or show car' differs from car to car... and although NOT a researchers
favourite, it is understandable....
transparency obviously has a limit...

has apparently a long list of options etc. but as far as I can see it is not an official factory press- or show car
BUT it can of course have been just used by the dealer as a show car - special dealer order cars are normally not
specificallly identified as such -
