Well look what we spotted on our way into the office this morning. Yep, that's a 2012 BMW M5. Look at all of those exhaust pipes.
Sadly, this is the only image we got. Something about a guy with an SLR alerted this driver to what we were up to and he took full advantage of that twin-turbo 4.4-liter V8 and bolted.
