Further proof that General Motors is readying a Opel Astra derivative for the Buick brand has just arrived in the form of spy shots showing a mid-size mule testing at Germany's Nürburgring. Somewhat obscured behind the excessive camo is Buick's trademark "waterfall" grille, however, the A-pillar and C-pillar survive the transition from Opel to Buick.
Inside, the badge engineering is markedly more apparent with what looks like an instrument panel, center console, and steering wheel directly ported over from the recently revealed 2010 Opel Astra. In all likelihood, the Buick version will be sold almost exclusively in the Chinese market and, although it would be built along side the Cruze at GM's Lordstown, OH plant, it's doubtful that the compact Buick will ever be sold in the States. But if it does, we'd suggest reviving the Skylark or Somerset moniker, because, hey... we know how well they went over before.
