Vauxhall Carlton Diplomat

The Carlton Diplomat was introduced in October 1991. The purpose of this car was to provide a more tax-efficient luxury alternative to the Senator and to compete with the Ford Granada Scorpio. The majority of Diplomats were produced on 2.0i guise although the much rarer 2.6i is an eligible vehicle for membership into the AutobahnStormers. The Carlton Diplomat was only produced as a 4-door model.
