Infiniti names Sebastian Vettel as a brand ambassador

The automotive brand ambassador scheme is a funny one in our minds - it seems to basically involve a company getting a celebrity to drive around in their car and get photographed putting bags of shopping in the boot in Chelsea.

We're not sure anyone would buy a Vauxhall just because Katie Melua drives one, but we think Infiniti has scored a bit of a hit with its latest ambassador - F1 world champion Sebastian Vettel.
