Given that you are from Melbourne, i assume you work at the engine plant. If that is true, what would you know about the build quality of a VE? Any random bogan walking down the street in Brisbane or Perth probably knows more about the build quality and process of the VE than you do. I worked at the Elizabeth plant and have driven hundreds of these things ranging from bog standard Omegas, through to GTS/Senators, right up to the best you can get, the SS Caprice and Caprice Royale that go to the middle east. The build quality is excellent, keeping in mind this is a mass produced family sedan, and it is still in series 1. The chassis and engineering underpinning the VE is very solid, and they handle excellently, as any one of 50 magazines attest to, and can take mass HP no problem. What more do you want from a family sedan? The SS ute and sedan are absolute weapons even before tweaking them. On average, the SS is making ~290kw at the engine (~230rwkw), straight from the factory, quite a bit more than what Holden quote. Exhaust, CAI, retune, a nice easy 330+kw.
Don't knock the VE, particularly the V8's, until you've driven one for a while. Sure, it's no GTR (i had a 32 GTR), but then, it was never meant to be. The new Camaro is based on the VE architecture. Forget the VT-VZ, the VE is a different beast entirely.
Yes, alot of the parts come from Asia....welcome to the automotive industry mate.
