Joplin’s rich ride:

Janis Joplin’s wildly painted 1964 Porsche 356C Cabriolet fetched $1.76 million, well above its top estimate of $600,000, at the RM Sotheby’s sale of vintage cars Thursday night. The singer bought the white Porsche used for $3,500 in September 1968 and got a friend to customize it with a psychedelic mural.
