The story

1967–1994: Thai Motor Corporation

The company was established by Vichien Phaoenchoke in 1967 as Thai Motor Corporation (THAMCO) and began assembling Leyland vehicles. After Leyland's decline, THAMCO switched its business to assembling Isuzu, Toyota, Nissan, and Chevrolet vehicles in the 1980s and 1990s.

1994–present: Thai Rung Union Car

The company was first listed on the Stock Exchange of Thailand on 21 November 1994 (1994-11-21), after it changed its name from THAMCO. It remains 70% owned by the Phaoenchoke family, with Sompong Phaoenchoke as its CEO.
