That dealer is either stupid or lying about the production.
2005 production is complete, about 2200 cars. 2006 production is ongoing through August 2006 for US cars, and they may make a few more after that for Canada or Europe if necessary to complete the run.
Through last week, they had made 1845 this year and 517 last year, see
