There's something about the RUF CTR—particularly this one—and its incomparable focus that make the hairs on my neck stand up. Among the numerous qualities, one of the more interesting is the weight—Alois Ruf's single-minded dedication to the CTR's comprehensive diet inspires me to start counting my calories. In fact, the motor is a bored 3.2-liter 930/20 engine with two K26 turbos, as the 930/60 3.3-liter turbocharged engine was too hefty for RUF. Simple fixed-back Recaros, a narrow G-model body, aluminum panels, and timeless, five-spoke Speedlines all trim the already-slim figure and complete a perfectly minimalist package.

Yet, it's much, much more than a stripped-out special. There's something slightly absurd about the colossal power thrust through those rear wheels—some 469 horsepower, though most claim that figure is closer to 550. Coupled with a streamlined body, this twin turbo engine propelled a CTR to 211 miles an hour at Nardo thirty years ago. That figure still surprises people.

There are also those little motorsport touches which provide some extra cachet: a Wilwood brake bias adjuster, an aluminum rollcage, and the fueling and ignition from a 962. The seamless blend of brute power, focus, simplicity, and sophistication is enviable—and the coat of mint green paint doesn't hurt, either. For those with a cool half-million ready for a serious automotive investment, there are few all-around marvels like this one.
