Via Bimmerpost.com we came across a spyshot of the 2012 BMW 6 Series convertible fully undisguised. The image was revealed by Autobild. It appears to be a leak of the upcoming 2012 6-series convertible.
The roofless sports car appears to be an BMW 650i cabrio (with style 356 wheels), which will begin production in March 2011. The F13 BMW 6-series will come with a traditional cloth roof.
