It's the Mercedes Club of Russia site. If you want to see the kind of results it returns, try this VIN: WDB1260391A527709. Pretty impressive, really. A lot of work went into that site, although it does not seem to cover all models and doesn't seem to work yet on cars made for the American market.

You might need to make a donation to get them to finish it.
