I've seen many pictures of Steve McQueen with a unique looking Jaguar. What type of Jaguar was it and what happened to this car?

The car is a Jaguar XK-SS, a limited edition touring version of the D-type Jaguar that won LeMans in 1955, 56, and 57. Only 18 were ever built. Steve McQueen used it as an every day car for a few years and sold it in the sixties. A decade later, Steve repurchased the car for many times what he had sold it for and had plans to restore it but never got the chance. In 1984, the car was sold at the McQueen estate auction for $147,500 to a collector and he restored it to McQueen's specifications.

UPDATE: It is now located at the Peterson Automotive Museum, and valued at about $30 million.

How many academy awards was "The Sand Pebbles" nominated for?

Which acting schools did Steve McQueen attend?

He went to the Neighborhood Playhouse, The Herbert-Bergoff Drama School (on a scholarship), and the Actors Studio (he was one of two people, out of 2000 applicants, who were accepted). They are located in New York.
