WIN the last ever Volvo C30 on Twitter

The last ever Volvo C30 (pictured) is up for grabs in a Twitter competition The Volvo C30 has only been with us for seven years, but it’s made its mark. Perhaps the highest profile outing for the C30 was with a starring role in the Twilight films, which exposed the C30 to a very non-Volvo demographic, and made the C30 almost cool. But with Volvo’s new V40 hitting the roads, Volvo revealed they were ending production of the C30 and now they’ve decided they’re going to give away the very last C30 – an R-Design model with Polestar upgrades and an Ice White paint job – in a Twitter competition starting on 13th June.

Audi RS7 Sportback (2013) first official pictures

This is the new Audi RS7 Sportback, just unveiled at the 2013 Detroit auto show.

That's faster than the latest Porsche 911 – it seems life just got a bit harder for the Mercedes CLS63 AMG and BMW M6 Gran Coupe.
