In 1915, Mercer, the most prominent American manufacturer of performance-oriented automobiles of the decade, introduced its first all-new model since the company started five years prior. The aptly named Series 5 would remain in production for nearly a decade and establish itself, just as earlier Mercers had, as the foremost American speed machine of a new era. Incorporating a brilliant Eric Delling-designed L-head four-cylinder engine with abundant power and flexibility on an advanced chassis with live-axle suspension, it was one of the fastest, most powerful automobiles on the American road.

According to historian Stan Smith’s 2019 Mercer Associates roster, the car offered here is one of six known surviving 1921 Series 5 examples in this style, the four-passenger touring car that Mercer aptly but unconventionally dubbed Sporting. Its earliest known owner is recorded as Joe Faltin of Manchester, New Hampshire, proprietor of a trucking company and early enthusiast of these models. After Mr. Faltin, longtime L-head Mercer historian and connoisseur John Rendemonti of Pennsylvania purchased the car. Mr. Rendemonti at one point passed the Series 5 to his friend, the late, well-known trader Mark J. Smith, but it eventually returned to his ownership. The consignor acquired it thereafter, adding it to his large collection alongside several other L-head Mercers.

Under current ownership the car was made to run and fitted with new upholstery. It exhibits a pleasing patina appropriate to what is believed to be the original green paint on the main body tub and doors. The floorboards, still intact with their factory linoleum covering, also appear original. A top and bows are no longer present, and the serial number plate is a reproduction, stamped with the engine number. Nonetheless, this is indisputably an original Series 5 Mercer, well-known to those in the know and, indeed, owned by several such enthusiasts over its long, rich life. It would be ideal for further recommissioning and enjoyment on the road, offering the sporting style that one expects from, well, a Sporting.
