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.

Europe’s economic problems sees UK become biggest Ferrari market in Europe

The Ferrari F12 (pictured) helped Ferrari to strong profits in the first half of 2013 The economic crisis in the Eurozone has seen Ferrari’s sales in countries like Italy and Spain plummet, and Greece managed just one sale in 2012 (and even that came to the UK). But Ferrari have a plan to keep profitability by limiting supply and achieving stronger revenues for the sale they do make – with stuff like Ferrari’s bespoke Atelier and Tailor Made services and Classiche work adding more revenue – to keep them powering forward, and it seems to be working despite poor sales in many European countries. In fact, despite an increase of just 2.8 per cent in volume, Ferrari has managed to increase their profits in the first six months of 2013 by an impressive 20 per cent, with total sales of 3,767 and net profits of €1.22 million.

Ariel Motors has teamed up with the Somerset Constabulary in the south of England to equip an Atom 3.5R, which features a 2.0-liter 350-hp engine from the Honda Civic Type R, with the necessary police gear.
