Like i have said previously, i am not forcing anyone to buy the UK one.
The reason why i am going with the UK one, even if it's exactly the same as the HK ones, is the fact that there is a one year warranty with the product so if anything goes wrong then you have a full year where you can get your product repaired or replaced.
As for software being out of date, none of the new model Opel cars are available to buy in Australia, so no one will have any need for the brand new software.
