I bought my 2007 sl550 with 3800 miles on nov 5 2009 on nov 6 2009 I was hit head on by an accelerating Jeep Cherokee that turned into my lane across a double yellow line, car was totaled but I walked away with some disc and whiplash injuries. There is no doubt this car saved my life, I traded a 2004 Corvette and a 2005 slk350 to get this sl550. If I was in any other car I would have been killed. There is no doubt this car saved my life, I am buying another one and will never buy any other car. Thank you Mercedes for your build quality and crash worthiness.
