Ahh didnt know there was a Holden factory here too!

There could be a huge debate about the whole GM/Holden/Chevy/Opel/Vauxhall thing. Fact of the matter is, its just funny when you are so used to seeing a brand you are familiar with, totally re-badged and being passed off as something else!

We'll just have to settle for them all being GM, cos they cant collectively be Chevys or Opels or Holdens as they are individual brands. Much like Ford owns Jaguar, Rolls Royce and Lotus etc. Although at least those cars have their own identity! GM has no imagination!

In fact, GM also stands for Genetically Modified, which is exactly what they have done with their cars! Modified them a little to make them genetically part of a different family, whilst fundamentally being the same car!

Ok, so maybe thats a bit off track....

Oh and I'm pretty sure (I may be completely wrong) that GM dont actually produce their own engines, they are a chassis manufacturer which tend to use japanese engines like Isuzu and Toyota, so may well be why you have those 2 cavaliers. Not uncommon for a 'Technology swap' between maufacturers.
