Pavlovo Bus Factory specializes in designing and manufacturing buses of the small/medium class (length 9.7 m).

The small PAZ buses have long been used by Russian "fixed-route taxi" (marshrutka) operators.

[2] The factory has its origins in the ZATI automobile and tractor tool plant, established in Pavlovo in 1932.

[3] The building of the factory started in 1952, and in the same year the first PAZ-651 long-hood buses (based on the GAZ-51 general-purpose lorry) were produced.

It was replaced by the outwardly similar PAZ-672 (based on the GAZ-53 lorry) in early 1968, and this bus had a large family of various modifications.
