Ever look for something high and low only to find it hiding in plain sight? That’s how we’d sum up the latest announcement from General Motors. The company has announced that the new Buick Regal – based on 2009’s European Car of the Year, the Opel Insignia – will enter production at the beginning of 2011 at its assembly plant in Oshawa, Ontario. There it will join the existing assembly line for the Chevrolet Equinox and GMC Terrain crossovers and the Chevy Camaro.

The kicker? General Motors subtly slipped in the announcement that the Camaro Convertible will begin production there as well around the same time. The drop-top pony car was first mooted with the concept unveiled at the 2007 Detroit Auto Show, and GM has been hemming and hawing about its production prospects ever since. Well, apparently they’ve made up their minds, and told all of us about it in the most understated way they could think of. Follow the jump to read the official press release.
