The GT (also known as the 560) was a car made by Monica between 1974 and 1975.

Although intended to be built in France, design, development and prototype building was entrusted to Chris Lawrence at C.J. Lawrence Consultants of Hammersmith, London, England. The 4-door, 4-seat saloon featured a De Dion rear suspension. Final styling and trimming was by David Coward.

The earliest prototype Monicas were powered by a Ted Martin designed 3.4L V8 engine but later prototypes and the production model were equipped with a Chrysler 5.6L (340 in³) V8 engine. Advertised transmission options were the Chrysler Torqueflite system or a ZF 5-speed manual gear box.

The styling and prototype body mouldings were produced by Bob Curl in Hastings. Several show cars were repainted after the Motor Show by John Drew, from the Bristol area, after the owner had seen his work for Bristol Cars at the show. John was then invited over to the factory to advise on production of the Monica, and recalls that, as many different nationalities were represented on the workforce, any production problem would result in heated multilingual discussions.

The Monica 560 was presented at the Salon de Paris 1972 and production began in 1973 at a facility located in Balbigny, Loire.

Only 8 production cars (as well as 22 prototypes) were completed before the factory closed in 1974, a victim of the 1973 oil crisis.

A plan by Panther Westwinds to resume production in England was announced in March 1975 but never implemented.
