Autoblog reader Mike dropped us a note the other day to let us he had spotted this car tooling around in Troy MI. Being a vigilant Autoblog reader he had a camera handy and snapped off a series of photos. Mike was unable to identify the car in question, but we've seen this machine before. It's the next generation Buick LaCrosse although it's not known if GM will retain that branding. The new Buick is built on GM's Epsilon II platform which is shared with the new Opel Insignia. Thanks to Mike for the photos!
