Editing Opel (section)

==Nomenclature==
From the late 1930s to the 1980s, terms from the [[German Navy]] (''[[Kapitän]], [[Admiral]], [[Kadett]]'') and from other official sectors (''[[Diplomat]], [[Senator]]'') were often used as model names. Since the late 1980s, the model names of Opel passenger cars end with an a. As Opels were no longer being sold in Great Britain, the need to have separate model names for essentially identical Vauxhall and Opel cars (although some exceptions were made to suit the British market) was made redundant. The last series to be renamed across the two companies was the Opel Kadett, being the only Opel to take the name of its Vauxhall counterpart, as Opel Astra. Although only two generations of Astra were built prior to the 1991 model, the new car was referred to across Europe as the Astra F, referring to its Kadett lineage. Until 1993, the Opel Corsa was known as the Vauxhall Nova in Great Britain, as Vauxhall had initially felt that Corsa sounded too much like "coarse", and would not catch on.

Exceptions to the nomenclature of ending names with an "a" include the under-licence built [[Opel Monterey|Monterey]], the [[Opel Speedster|Speedster]] (also known as the [[Vauxhall VX220]] in Great Britain), [[Opel GT|GT]] (which was not sold at all as a Vauxhall, despite the VX Lightning concept), the [[Opel Signum|Signum]], [[Opel Karl|Karl]], and the [[Opel Adam|Adam]]. The Adam was initially supposed to be called, "Junior" as was its developmental codename and because the name 'Adam' had no history/importance to the Vauxhall marque.

Similar to the passenger cars, the model names of commercial vehicles end with an o (Combo, Vivaro, Movano), except the Corsavan and Astravan.

Another unique aspect to Opel nomenclature is its use of the "Caravan" (originally styled as 'Car-A-Van') name to denote its [[station wagon]] body configuration, (similar to Volkswagen's ''Variant'' or Audi's ''Avant'' designations), a practice the company observed for many decades, which finally ceased with the 2008 Insignia and 2009 Astra, where the name "Sports Tourer" is now used for the estate/station wagon versions.
