2013 Mercedes-Benz SL65 AMG

Make way for the 2013 Mercedes-Benz SL65 AMG, the most wonderfully preposterous car I have ever driven.
There is absolutely no reason why any two-seat roadster should be fitted with a twin-turbocharged 6.0-liter V12 developing 621 horsepower and 738 pound-feet of torque, but I sure am glad that Mercedes-Benz doesn't see things that way.
Drop into the leather-lined cockpit of this $213,145 provocateur, floor the accelerator pedal as I did over and over again, and 60 miles per hour falls in a traction-limited 3.9 seconds. Top speed has been electronically held to 186 mph (this apparently saves Gulfstream jet owners from embarrassment). Forget the SL550 and SL63 AMG, the valets will trip over themselves attending to the tycoon driving this thoroughbred - it's the real deal.

Volvo S60 Polestar concept plays in the snow with Mercedes C63 AMG

Chris Harris took to a snowy stretch of tarmac to get a fingertips-on-the-wheel feel of the Volvo S60 Polestar concept. Harris says the turbocharged sedan with 508 horsepower and 424 pound-feet of torque - and a manual transmission - is "a study to see if Volvo can get back into the fast-car market." The Polestar S60 concept, one of which was already purchased for $300,000 by a private buyer, is still making the publicity rounds because even Volvo's Chinese owners realize that, as Harris says, "Volvo sold more cars because it made fast cars" like the old 850 T5 Wagon that stormed the British Touring Car Championship in the 1990s.
For reference, Harris compares the blue wonder to the Mercedes-Benz C63 AMG and its 487 hp and 442 lb-ft. The question is, were Volvo to get the price of a production version of the S60 Polestar to climb way down from its 200,000-pound sticker, could it be worthy competition to the established giants?
You can watch Harris divine the answer via a lot of drifting through the snow and a drag race in the video below.

Clark Gable's 1955 Mercedes-Benz 300SL Gullwing doesn't sell, then does sell for $1.85 million [UPDATE: w/video]

How much extra value does previous celebrity ownership add to of a car? Really, there's no way to know until the car in question hits the auction block and bidders start raising their hands. In the case of the 1955 Mercedes-Benz 300SL Gullwing you see above, the celebrity owner is none other than Clark Gable, who purchased it new. After Gable's death in 1960, the car changed hands a few times before settling with Charles Wood in 1975.
A high-dollar restoration was performed in 1989, and period accessories added by Gable himself were kept in place, including the Rudge knock-off wheels and Nardi steering wheel. Any Mercedes-Benz 300SL is worth a big chunk of money. In the case of Clark Gable's old Gullwing, the bidding stalled at $1.9 million here at the 2013 Barrett-Jackson auction in Scottsdale. As one of the 5000-series cars, this 300SL carried a reserve, and a bit of after-the-fact dealmaking saw the car change hands for $1.85 million.
