From 1927 to 1930, the French car manufacturer Rally built a two-seater sports car that proved its worth both on the road and in racing. In keeping with the cycle car tradition, the company dispensed with unnecessary luxury and created a car that was easy to drive and lightweight. One of the 100 or so Rally ABCs built will go under the hammer at Bonhams on October 6, 2017. This vehicle report portrays a Rally ABC Sports from 1929 and describes the history of the model and the specific vehicle.
