It’s a shame that infomercial pitchman Billy Mays passed away just as Mercedes-Benz is launching the performance version of the 2010 E-class, because he would have done an excellent job of touting the many uses for the new and improved 2010 E63 AMG. “The 518-hp V-8,” Mays would say in his booming voice, “rockets you from 0 to 60 mph in 4.4 seconds, making quick work of sports cars with less than half the seating. And you can still use it every day to pick Junior up from school and drop Grandma off at the library.” Not that the E63 is the sort of car that would be hawked via cable-TV ads, but it does promise a “You won’t believe your eyes!” combination of performance and usability. There are no easy payments, however, despite the fact that when the E63 goes on sale in October, pricing should fall below that of its predecessor. Expect to pay just under $88,000 to start.

With 552 hp, a body to die for, and a 0–60 time of 3.2 seconds, the Lamborghini Gallardo LP560-4 has little room for improvement. But there is room for variation, and perhaps the most significant is the new Gallardo LP550-2 Valentino Balboni. Limited to just 250 units worldwide, the LP550-2 Valentino Balboni is named after Lamborghini’s esteemed test driver, who was hired by Ferruccio Lamborghini himself in 1967, and who has been instrumental in developing the dynamic attributes of every Lamborghini model introduced since 1973.

First Rear-Wheel-Drive Lambo Since the Diablo

Fittingly, Lamborghini honored Balboni by dialing up the excitement factor of what is already a pretty exciting car. Those familiar with Lambo’s current naming practice, which combines a car’s metric horsepower and its number of driven wheels, have probably figured out the LP550-2’s biggest news: rear-wheel drive replaces the standard Gallardo’s four-wheel drive. Yes, the name also tells us that the LP550-2 Valentino Balboni is down 9 hp compared with the LP560-4 (543 versus 552 at 8000 rpm). But with an expected curb wieght nearly 70 pounds less than the last LP560-4 we tested, which weighed in at 3507 pounds, the lost ponies aren’t likely to be missed. Torque remains the same at 398 lb-ft at 6500 rpm.

A brand-new standard-issue Chevrolet Corvette remains an incredible performance-car bargain. For less than two-thirds of the price of a Porsche 911, the latest C6 thunders to 60 mph in 4.0 seconds flat, corners at 0.99 g, and tops out at 190 mph. And for a two-seat rocket, a Vette is also very practical, with 57 percent more luggage capacity than a Honda Accord and tall gearing that, during relaxed highway cruising, squeezes more than 25 miles from each gallon of premium fuel.

Even so, the Corvette’s current base price of $49,515 might be more than some people can or want to spend. If you fall into this group, you’ll be happy to discover the many used Vettes on the market, given that today’s C6 generation was born in the 2005 model year. When you peruse secondhand Corvettes, you’ll also find that many of them have very low mileage, having been driven mostly on summer weekends in cold states. Three- and four-year-old cars with less than 10,000 miles are not unusual.

To reduce the risks of used-car buying, GM offers a certified used-vehicle (CUV) program. Similar to all such programs, GM’s starts with a detailed, 117-item checklist to make sure that everything is operating as it did when new. The car gets a thorough cleaning and detailing, brakes and tires that are more than half-worn are replaced, and the next scheduled maintenance is performed.
