This rare 1980 Vauxhall Royale Coupe, marketed as the Opel Monza A1 in the UK, has undergone a sympathetic restoration between 2002 and 2010 by a renowned Jaguar restorer, preserving its original Aquamarine Blue paint and blue crushed velour interior. Showing 70,110 miles, this executive coupe features a 2.8-litre carburettor-fed straight-six engine mated to a three-speed automatic gearbox and boasts a well-documented history file, including its initial use as a company car for a GKN Fasteners director.
