• Metropolitan Opera 40th Anniversary Gala. Metropolitan Opera, Lincoln Center, 7 p.m. Expected guests include Julianna Margulies and Ivanka Trump. And there are still tickets for the public left in the "Orchestra Balance" and "Orchestra Prime" sections! Ah, Orchestra Prime: the most highbrow of the Transformers.

• Mercedes-Benz "Famous Cars + Famous People" preview. Drive-In Studios, 443 W. 18th St., nr. Ninth Ave., 7 p.m. Chloë Sevigny and Tinsley Mortimer will host. The exhibit features numerous Mercedes-related works by the likes of Andy Warhol and David Hockney, though observers have criticized the glaring omission of Picasso's Nude With Anti-Lock Brake System.
