Unlike most other automobile magazines, Automobile does not often do instrumented tests of cars or provide much technical data. Instead, the reviews of vehicles are subjective experiential reports with the cars in their naturally intended, real world environment. Additionally, Automobile reserves a good portion of each issue covering vehicles no longer in production, but still relevant to collectors or automotive history as a whole. For example, the magazine includes features such as "Collectible Classic," an in-depth review of aparticular older car, and reports from recent classic and antique car auctions. Automobile also has a regular column by former General Motors designer Robert Cumberford, who analyzes styling elements of current production models and show cars, often linking their design to those of older cars.
