The Challenger is now official and should be built at Brampton, pending union agreement to a more flexible contract and probably the usual government tax exemptions. Chrysler announced production would start in 2008 at 50,000 units per year - a more generous number than some had expected. The car is expected to cost Chrylser about $145 million, a remarkably small amount for a new car, because the factory is already flexible and tooling can largely be shared with other LX models.
