Archer. Titled "Double Trouble" (season 2, episode 13), the official synopsis is "Krieger works to finish a top-secret project, and Archer brings a mysterious former KGB agent named Katya Kazanova home to meet Malory, unaware that Barry Dillon is heading his way to kill him."
Early on in the episode Dr. Krieger mentions listening to "Red Barchetta" through his "awesome van's" stereo, and mentions to Archer's Russian defector love interest Katya "Please tell me you like Rush". Later, we see the actual van, and it's painted like the Exit...Stage Left album cover, only it says "Exit...Van Left". Click here to watch the episode. - Thanks to Timmy Samuel for the headsup!
