Thanks for the info Rocketman - I didn't know the steering wheels in US versions did not have the splined shaft which Aussie versions have.....with no airbags it makes other steering wheels an easier choice compared to more modern cars with air bags now. It is illegal in Australia to remove airbags if fitted.
WashiestSnake - all Australian cars have historically used a 2 character model designation as opposed to model year references. For instance the Capri was designated SA, SAII or SA2, SC and then SE in final form. The Holden Commodore (which is also the Chev SS in US currently) used a V designation beginning with VB in 1978 (then VC, VH, VK, VL, VN, VP, VR, VS, VT, VX, VY, VZ, VE) and finishing with VF in 2017 - they are not always in sequence but are used to differentiate. I believe it stems from an original GM system where the first letter designates a platform and the second letter represented the year of design, again not in alphabetical sequencing. This isn't the case in modern cars but more just to differentiate series of vehicles. Often we Australians will describe our cars by this model code, for assistance "I have a VE" meaning "I have a Holden VE Commodore". This applies to other older Australian cars like Ford Falcon (XT, XW, XY for instance) or Chrysler Chargers/Valiants (VJ, VH, etc).
Having said that, Model Year (i.e. MY15) is becoming more popular from car sales and advertisements and will probably grow once local production of cars ceases soon (Ford in 2016, Holden in 2017 and Toyota in 2017).
Hope this makes sense....
