Input: Question: Which of The Cars' greatest hit singles has sold the most? Passage:Their third album, Panorama, was released in 1980. Although it peaked at number 5 on the Billboard 200 and has been certified Platinum, it was less commercially successful than its predecessors. A single, "Touch and Go", peaked at number 37 on the Billboard Hot 100. Their next album, Shake It Up (1981), fared better commercially, going platinum by the end of the year and spawning their first Top 10 single with its title track. 1984's Heartbeat City was the band's most successful, hitting number 3 on the Billboard 200. Its lead single, "You Might Think", reached number 7 in the US, with three more singles: "Magic", "Drive", and "Hello Again" reaching number 12, 3, and 20, respectively on the Billboard Hot 100. Their Greatest Hits album, released later that year, contained the singles "Tonight She Comes" and a remixed version of "I'm Not the One", and has gone 6x platinum. Their final album before their breakup, Door to Door (1987), spawned the single "You Are the Girl" which reached number 17 on the Hot 100; it was their last Top 40 hit as a band.
