Mark Davis has forwarded a set of images that's doing the rounds via email. The subject line is: WHY OIL IS SO EXPENSIVE. And the text reads:
Audi A8 in SILVER made for a sheik
IT IS NOT SILVER COLOUR IT IS MADE OF SILVER!!!!!
You can see the pictures below. A search on the internet doesn't pull up any other references to these pictures. So I have no idea if the car really is made of silver, though it seems more likely to me that it's polished chrome, making this a case of 'real picture, fake caption'. But whether or not it's silver or chrome, it's doubtless a very expensive (and cool looking) car. Someone very rich must have ordered it.

Here's the info on this one from MTM, the Audi tuner specialists who did the one you have pictured:

Still, it's lovely. Probably very prone to scratching though.
And to show off what a geek I am, a tube of toothpaste would do the trick - it works wonders on tarnished silver. 😉
The melting point of silver (1763F) is quite a bit higher than aluminum (1220F)
Silver does tarnish, but it is the most reflective metal (used for high quality mirrors, aluminum is used for lower). Aluminum also tarnishes anyway (forms an oxide layer that is not as reflective), both would need a top coating.
However, as the first post said, it is probably aluminum. Solid silver would be quite soft.
If anyone ever did want a real silver car, they'd probably plate it over steel (or even better, plate a thin coat of nickel over steel, and an even thinner coat of chrome, which doesn't tarnish and is much more scratch resistant).
But, it can't be totally ruled out. Something similar has been done with gold: http://www.bigtexas.com/dmc/
Toothpaste is much too abrasive to use on valuable silver-- you'd end up with a lot of fine scratches on the surface. Tooth enamel is much harder than silver.
To clean silver, either get some good silver polish, or just use soap and warm water and a soft cloth.
Another household hint from...
So, how is house arrest?
(Heh heh, my confirmation word was 'big')
"Aha, Gary is Martha Stewart!
So, how is house arrest?"
My house is still at large, although many people think it SHOULD be arrested.
The myth has been crushed..

Audi A8 is made of alluminum. they stripped the paint and polished it to a shine.
It did work, but cost a lot more than aluminium foil would. On the other hand, back then most of us didn't have rolls of aluminium foil if the kitchen, so I'm not sure whether to count it as a hoax.
