Watch 'The Million Dollar Mustang' part one: Shelby GT350 R

“The Million Dollar Mustang” is not about how much these great cars go for at auctions in today's heady times, but about what made them worth so much in the first place. Nearly five years in the making, the documentary starts out talking about the Ford Mustang in general, how they sold 22,000 of them on the first sales day and then sold a million of them in the first two years and things like that -- the notion that the Mustang was a revolution in American car design and in the American consciousness. Then it starts to narrow its focus more and pretty soon the bulk of the piece is all about the Shelby GT350 R.

First Sight: Holden Torana concept

Holden has stolen the limelight at the opening of the Australian International Motor Show in Sydney, unveiling a ground-up concept car dubbed the Torana TT36.

That's where the similarities end, however, as the new Torana's engine is an experimental 280kW/490Nm twin turbocharged version of the new global V6 Holden has begun manufacturing for various parts of the GM world and which will eventually be used by Alfa Romeo.
