That car is old news...that A8 is polished aluminum not pure silver! Could you imagine how much the car would weigh if it were pure silver?
I believe an arab now owns that vehicle. I saw it back in the mid 90's at Geneva and then recently on this site there was a picture of an arabs driveway with loads of exotics in it and the aluminium A8 in the background. Lovely car! Oh i just read the post above. I'm pretty sure that A8 is a different one as it is a later version and not the first release which had one in aluminium (hence the confusion).
