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. Spotted in the wild, this XTS raises more questions, perhaps a performance model is in the works?

Ford off-roading fans can rejoice. The 2013 Ford F-150 SVT Raptor will offer more “dirt don't hurt” options with factory available beadlocks and HID headlights. Prices are expected later this year.

While the “Ultimate Miata” may bring to mind a “Hello Kitty” edition two-seater, the Miata MX-5 GT concept that will debut at Goodwood will be anything but. The 205 horsepower concept looks promising, we can't wait to see more.

Autoweek went to school at the BMW Performance Driving School in South Carolina; and now you can too. If you are dying to drive the new M5, M3 and limited-production 1M head on down to the Palmetto State. Everyone is invited.
