1948 Buick Series 70 Roadmaster Convertible Coupe

  • Chassis Number: 50270587
The 1948 Buick Roadmaster was a Harley Earl design featuring a 320 cubic-inch engine mated to a 2-speed Dynaflow automatic transmission. This convertible was purchased in May of 1998 by the current owner.

In 1948 a series script appeared on the front fenders and the white Tenelite steering wheel that had been used previously was traded in for a black one, in order match the change from a two-tone woodgrain instrument panel to a two-tone gray instrument panel, with silver tone instruments. A new optional Custom Trim option was offered, consisting of cloth upholstery with leather bolsters with the robe cord cover and lower door panels done in leatherette. The convertible models received power windows, seat and top as standard equipment.
