The Toyopet Master, introduced in January 1955, is a passenger car that was an update to the SF/RH model with a modernized body. As for its predecessor, it has a ladder frame with leaf sprung front and rear axles. The Toyopet Master was an evolution of an earlier Toyota sedan called the Toyota SF/RH model (also known as the Super), and was sold in parallel with the first Toyota Crown. The more conservative Master was introduced as a frugally equipped version meant for taxi usage.
