the time. The option of importing Opel cars was dismissed on the basis that it was perceived to be an entry-level brand, relative to BMW's premium status. Ultimately, fewer than a dozen Buick dealers (mostly in the metro New York City area) would bear the Bitter signage, resulting in minimal sales. Bitter's failure was based on its business model, and the diminishing trend of rebodying other manufacturers' vehicles, which became unpopular by the 1980s. Total production by bodyshape CD II In 2003, in an attempt to resume its small-scale production, Bitter presented a modern reincarnation of the CD, known as the CD II. It was based on the Australian-made Holden Monaro but rumoured to feature a V12 engine. Investors were sought but the car never reached full production. Vero In 2007, Bitter resumed small-scale production by launching the Vero at the 2008 Geneva Motor Show. This car was derived from the Australian-made Holden Caprice (WM) sedan (the long-wheelbase luxury derivative of the Holden Commodore (VE)), believed to be purchased directly from Holden thanks to Erich Bitter's friendship with Holden's former Peter Hanenberger. Relative to the donor car, the Vero features unique restyling claimed to have cost A$1 million, which take about a week to apply. In particular, the vehicle is shod 20 inch alloy wheels and has a prolonged bonnet along with a redesigned front bumper incorporating a new grille, and an additional rear bumper insert to house rear foglights required in Europe. Its leather-trimmed interior featured luxury fittings from the donor car such as a DVD player and screens in the back of the front headrests for rear passengers. The donor car's Chevrolet V8 6.0-Litre 362 CV (266 kW) engine, with a six-speed automatic transmission, remained unchanged. The Vero was sold in Germany for €121,975 and was discontinued in 2012. Vero Sport In 2009, Bitter unveiled a "Vero Sport" at the Geneva Motor Show. Unlike the regular Holden Caprice (WM)-derived Vero, the Sport was directly based on the short-wheelbase Holden Commodore (VE) SS sedan, also sold as the Pontiac G8 in the United States. Like the Vero, the Vero Sport was also discontinued in 2012. Other models Bitter Insignia Bitter produced a luxury version of the Opel Insignia OPC between 2010 and 2013 as the Bitter Insignia.
