Ultra-low-mileage Chevrolet Corvair Monza heads to the auction block

We've never really paused to appreciate the subtle good looks of the Chevrolet Corvair, especially the end-of-the-line 1969 Corvair Monza coupe. But this particular car, which will be sold at the upcoming Mecum Houston auction on April 11, will make you stop and take stock. Even if you're Ralph Nader, you can't help but be impressed by its extreme originality: It has just 15 miles on the odometer.

McLaren MP4-12C GT3 (2011) track testing begins

McLaren has begun testing its latest track weapon, the MP4-12C GT3 ahead of the 2012 FIA GT3 season.  How different is the MP4-12C GT3 from the roadgoing edition? The MP4-12C GT3 is based on the standard machine but modified for FIA GT racing by McLaren GT - a joint venture between McLaren Automotive and CRS Racing, a UK-based team currently competing in FIA GT with Ferrari F430s.  Externally you'll notice the race-spec fixed rear wing, undertray diffuser, front splitter, louvres and vents. Underneath there's a new suspension system, ditching the road car's linked suspension for FIA-compliant conventional dampers and anti-roll bars. Akebono is supplying race-specific brake components, and Bosch Motorsport has installed its ABS system. The car sits 100mm wider on its new suspension and has suitably flared bodywork as a result.  It's still the McLaren's bespoke 3.8-litre twin-turbo V8 engine, tuned for racing.
