Oh sure, we've already shown you spy shots of the 2010 Buick LaCrosse that reveal the kit and kaboodle, but don't let that take away from GM's release of a teaser shot showing the upcoming sedan's new grille. Along with the pic, GM confirmed that the new LaCrosse will debut at the upcoming LA Auto Show in November. We'll be there to cover the reveal, as this smallest of Buick sedans (for now) will be a big player in the brand's future success. It's nice and all to have a critically acclaimed full-size crossover in the Enclave, but more and more buyers are moving away from big CUVs into smaller vehicles at the moment, and Buick hopes they'll move right into the new LaCrosse.

Though the newish Buick Enclave has received plenty of accolades, it's the right vehicle at the wrong time for GM's smallest brand. The other two vehicles in Buick's lineup - the LaCrosse mid-size sedan and Lucerne large sedan - might better appeal to gas-conscious buyers than a large CUV, but they're far from leaders in their segment. A new LaCrosse, however, will reportedly be arriving as a 2010 model.

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!
