What do you buy for the car collector who has everything?
Apparently, an RUF CTR-3.
Ralph Lauren, the fashion mogul and vintage-car collector, recently took delivery of an RUF CTR-3, according to people familiar with the deal. Lauren was snapped by the car-parazzi taking it for a spin recently in the Hamptons.
A spokesman for Lauren declined comment.
For super-rich car collectors, the RUF is one of those cult brands with a storied past and a reputation for high performance. Germany-based RUF Automobile has modified Porsches for 50 years, pimping them out with a super-charged flat-six cylinder engine and bulking up the frames with its own wings, fenders and vents.
The CTR-3 has a base price of $680,000 but most of them top $700,000 with customized specs. This is not merely a souped-up Porsche; the CTR-3 is built more from scratch. Only the front end and part of the engine originate from a Porsche 911.
Its swooping body with a long, Le Mans-style tail is made from carbon fiber. The car has a 777-horsepower engine and, according to the company, can "go faster than anyone can drive."

RUF has sold three of its CTR-3s in the U.S., but has only sold 25 since the product was launched in 2007. RUF has other models, of course, but only makes and sells about 30 to 35 cars a year.
"Our customers appreciate the performance of these cars, it's like a true race car," said Estonia Ruf of Ruf Automobile. "For people who like race history, this car has lines that evoke that past but it also has elements of a new model. It's not retro. But the lines are very beautiful."
The perfect new car, in other words, for a man who already has a garage full of vintage Ferraris and Bugattis.
