They’re not bad; they’re just drawn that way. Sixteen hopelessly racy roadsters and runabouts — all from the private garages of one Mr. Ralph Lauren — purr into the Museum of Fine Arts, Boston, on March 6.

Bring your lace-up gloves. “Speed, Style, and Beauty: Cars from the Ralph Lauren Collection,” through July 3. (617) 267-9300,
