Standard fitment for the 204 models was a 135SR14, with the option of a 145SR14. 304 models had the 145SR4 as standard.
The 204 and 304 were very modern Peugeots, with transverse font-wheel drive. Practical and good to drive, the 304 was a slightly larger and more powerful version. Huge sales success as a sloon that spawned very attractive coupe and convertible versions.
