None.
A perfect small four door sedan. This car was totaled with my wife driving a week ago (other driver's fault)equalling about a 40 mph. head on crash. The whole front end was gone. The driver and passenger's compartment were totally undiststorted! My wife has virtually no injuries, and in other cars I would be a widower. I have never seen a car after such a colission with the cabin so untouched! Immediately ordered a replacement, and will be MB drivers from now on.
BMW's and Volvo's are just as safe. Sorry to burst your bubble there, Hoss.
