Located at the northeast end of Downtown San Fierro, just across from Esplanade East, Otto's Autos encompasses a three-storey building with ample floorspace for spawned vehicles. Vehicles in the showrooms spawn randomly, since it depends on nearby traffic.
The showroom is central to "Test Drive", when, in one daring and attention-grabbing effort, the player and Cesar Vialpando make their way to Otto's Autos in order to purloin a Sultan and an Elegy. The two men drive the cars from the second floor showroom, bursting through the glass and landing on the Esplanade, and lead the San Fierro Police Department on a high-speed chase throughout the city, before finally returning the cars to be put on display in the Wang Cars showroom.
- The Otto's Autos signage incorporates silhouettes of a GTA Vice City Sentinel.
- The showroom displays large pictures of vehicle renders, including the ZR-350, Infernus, Turismo, and Bullet.
