history
From Bai Juyi's (白居易, Tang dynasty) 《琵琶行》 ('Song of the Pipa'), spoken by the aging pipa player about her faded youth: 门前冷落鞍马稀，老大嫁作商人妇 - 'visitors at my gate grew sparse; in middle age I married a merchant.' Classical shorthand for fallen fortunes.
usage
Bai Juyi's original text has 鞍马 ('saddle-horses'); later quotation standardized to 车马 ('carriages and horses'). Both forms are understood; 车马稀 is the version that entered general idiom.
