The first SRT Viper is sold, we spot an exotic XTS, and the 2013 SVT Raptor offers more off-road fun, this week's Autoweek in review

The first SRT Viper crossed the block at Barrett Jackson in Orange County this past week, for a cool $300,000. All the proceeds will go to the Austin Hatcher Foundation, a charity to help families and children affected by pediatric cancer. While the Cadillac XTS hasn't been a stranger on public roads around Michigan, this heavily camouflaged example is a bit of a mystery.

Aston Martin Lagonda SUV still moving forward

New reports suggest Aston Martin is still pushing forward with the Lagonda SUV, with underpinnings from the Mercedes GL. Last year we reported the Lagonda SUV was back on (although we’re not sure when it was actually off – just MIA) and that it was Aston Martin’s hope they could raid Mercedes parts bin for the underpinnings of the SUV, and take on the building of a new Maybach for Mercedes in the process. But as we now know, Mercedes has decided a Pullman S Class has more cachet (and less build cost) than  the glitter ball Maybach, so Aston Martin’s hopes of a nice profitable design and build deal evaporated with the last roll of the dice for the Maybach brand.

Porsche considering full factory F1, Le Mans teams

New Porsche CEO and president Matthias Muller is weighing up a review of Porsche’s motorsport activities – and claimed the sports car brand could re-enter Le Mans with a full factory team, or even F1. Muller was appointed on 1 October 2010 and has lots on his plate: he’s a VW veteran and is charged with integrating Porsche smoothly into the Volkswagen business empire as Wolfsburg ratchets up its ownership of Porsche. That integration includes motorsport, he told CAR at the 2010 Paris motor show.
