These days, the Sauber name is most famous for its Formula 1 team. But before F1, Sauber had a long history of sports car endurance racing with plenty of pedigree. In the '70s, they built this car, the C5, to compete in Le Mans. Only five exist, and this one's for sale. You should buy it.
Welcome to You Must Buy, our daily look at the cars you really should be buying instead of that boring commuter sedan.
An evolution of the earlier C4, this C5 just popped up for sale , painted in plain white with a singular BMW roundel pasted on the nose. That badge is there not because BMW built the car, but because it supplied the engine—an M12 inline-four also found in Formula 1 cars of the 1980s. It's a naturally aspirated, fuel-injected motor with dual overhead cams displacing 1998cc, capable of 300 horsepower and 170 lb-ft of torque according to the ad. Getting that power to the rear wheels is a Hewland FGA 400 five-speed manual.
Aside from the BMW engine, the biggest update from C4 to C5 was the shape. The streamlined fiberglass body and big, round headlight clusters round out the basic design, with three inlets at the front: One central hole to direct air over the body, and two on either side to cool the disc brakes.
This particular car has just undergone a "full refresh" according to the ad, with less than eight hours of track use on the engine and body. Pictures are limited to a few on-track panning shots, but from what we can see, it looks to be in fine condition. Sauber fielded a few of these cars in the 24 Hours of Le Mans, but the ad doesn't specify if this is one of them.
There's currently no price listed, but because of this car's rarity (and recent major service) we'd guess it won't be cheap. .
