The REO Motor Car Company was founded in 1904 by Ransom Eli Olds, who had earlier started Oldsmobile but left after a dispute with the board. Using his initials for the new venture, Olds focused on building reliable, moderately priced vehicles. While Oldsmobile stayed under the control of General Motors, REO remained independent. The two companies were often confused, but REO quickly carved out its own identity — especially with its early success in both passenger cars and commercial trucks.
REO’s commercial vehicles caught on quickly, especially in rural areas. In newspaper ads from the 1920s, the Speedwagon was promoted as the smart way to get grain to market or to keep delivery routes on schedule. It had a sturdy frame, a powerful engine for the time and was built for roads that were often little more than dirt tracks. The company leaned hard on its engineering, but also on its reputation. By then, REO had already spent 30 years making cars and trucks, and wasn’t shy about reminding customers of it.
As truck design evolved in the 1930s, REO kept pace. The brand introduced more aerodynamic lines and offered trucks in a range of sizes and configurations, including their well-known Flying Cloud models. Some were fitted for ice cream delivery, others for heavier commercial loads. The focus stayed on strength, economy and serviceability — traits that mattered to operators who depended on their trucks to earn a living.

Even as larger automakers started to dominate the market, REO trucks held onto a loyal following. Fleet operators were encouraged to “standardize on REO,” and ads made it clear that every part of the truck — from the cold-riveted frames to the heavy-duty axles — was built with long-term use in mind. They weren’t flashy, but they were dependable, and for many businesses, that mattered more.
REO continued building trucks into the 1950s, but by then the company was struggling to compete with larger manufacturers. Passenger car production had already stopped in the 1930s. In 1954, REO merged with Diamond T to form Diamond-Reo Trucks, which kept the name alive for a while longer. The brand eventually faded out in the 1970s, but by then, the original REO Speedwagon had already earned its place in both automotive history and pop culture — just not in the way the company might have expected.
Below, we’ve gathered vintage ads and original photos of REO’s trucks and cars from the 1920s and 1930s, including the original REO Speedwagon that gave the later rock band its name. These machines weren’t meant to be iconic — they were built to last, and they did.

Reo quality always pays off (1930s)
Reois making a name for itself with highway carriers whose income depends entirely on truck operations and truck economies.
Transportation is their business. Here Reo quality really pays off. Modern truck engineering, heavy-duty dimensions, quality materials and manufacture cut repairs to a minimum — provide the dependability essential to timetable schedules and the long life that helps protect the investment.

For timetable deliveries… standardize on Reo (1930s)
Reo, the truck that grew up with gasoline, helps the petroleum industry and many others to maintain timetable deliveries on local and long-distance routes.
Reo is built for capacity loads… the massive frames are cold-riveted for extra strength — axles, wheels and springs are the heavy-duty type — there is sound truck engineering in every chassis part.
Reo is designed for dependable performance… the precision-built engines provide ample power to deliver heavy loads on time and at low cost.
