Isuzu Piazza Turbo Owners' Club

The Isuzu Piazza Turbo Owners Club (IPTOC) is a club based in the UK for owners and enthusiasts of the Isuzu Piazza, Holden Piazza, and Isuzu Impulse from all over the world.

The Isuzu Piazza was marketed by Holden in Australia, and called the 'Impulse' in the USA. From 1980 to 1990 around 13,000 were produced without significant alteration to the original design, based on Giorgetto Giugiaro's Asso di Fiori concept car. Later versions received handling engineering by Lotus.

The club was formed in 1995 with the aim to bring together and support initially UK owners. Due to the limited number of cars in existence, IPTOC has extended internationally, and links to affiliate groups in Australia, New Zealand, USA, Japan and more. The club aims to hold a summer meet each year in the UK and has welcomed international guests.

Joining is done by contacting and registering, after which members are added to the mailing list and kept informed of meetings, events and offers.
