SIX CARS, FOUR HOURS, 2,303 HP.

Byline: MV

Even in our little sliver of car-world reality, things like this don't happen every day. As part of a program put on by World Class Driving, we spent the better part of a recent morning tooling around in $1.2 million worth of supercars. Hopping from one to the next and the next gave us a unique perspective on the supercar world, and just a vague glimmer of the painful choices made each morning by Jay Leno and the Sultan of Brunei. Poor bastards.

Aston Martin Vantage Roadster This was a 2008 V8 roadster, and the WCD people had not only put the top down for us, but had assigned as copilot a perky PR girl who, only a matter of months before our drive, had been in a sorority. So the whole Aston Martin ownership experience was highly accurate, down to the 22-year-old co-driver with the perfect teeth.

Callaway Corvette Coupe In place of the sorority sister, we had Reeves Callaway himself riding shotgun in this car. Reeves is always a pleasant and knowledgeable guy to have around, more so when he lets you into one of his cars. He just wasn't as cute. The car was the exact same one we'd just reviewed (AW, June 2) and still just as much fun to drive. A Callaway Corvette is a large, low beast with a huge engine sitting in front of youthat's the impression the car gave when we crawled into it. The traction control was in the "on'' position but it allowed a surprising amount of oversteer; we got all of it leaving the roadside stopping place. This thing makes 616 hp! That was a lot more than the Aston and, with this rig's manual transmission, more accessible than the Aston's automatic allowed.

Spyker C8 Spyder SWB The heart of this Dutch supercar is a magnificent Audi V8, which roars with a delightful defiance each time you floor the throttle. From the outside, the car has a distinct look you will not find anywhere other ...
