FORD SIERRA COSWORTH GRA

This Ford Sierra Cosworth GRA was built by Italian Cosworth specialist Oppliger Motorsport (https://www.oppligermotorsport.com).

It benefits from an Italian International PTH which has to be updated since the fitting of the large rear suspension, the tank in the boot, the side exhaust and its new decoration.

It is built to 1990 specifications.
