That's the smartest thing they could have done. There's no way they could have achieved any international penetration with the current production capacity. It also simplifies the component and feature matrix that the Brampton site must maintain. Once the 300 surge dies down at Brampton, they'll be poised to add the Charger into the mix and keep things running at full steam.
You guys beat me to the "punch". I spoke to my local Chrysler dealer last weekend and he told me that our 300C's will be built in Austria. Apparently the Grand Voyager we get in Australia is built there too and the dealer reckons visiting Americans pick up the specification differences and better build quality (meaning no disrespect to Canadian members) straight away.
Early advice is the Aussie specification 300C may have polished Magnum design wheels and be de-chromed, as they reckon Aussie like it like that. I like the US 300C with the chrome personally and will need to buy the deleted parts if they do go with their plan. The wheels are gonna be expensive to ship
