Most Tank Like Car?

Let's say I wanted a car that could take a licking and keep on ticking. Push other cars and trucks, take a hit, drive through a fence, over a curb at speed, through a ditch, across a median, etc. Let's also say this car needed to blend in, so no overt mods and at least somewhat common. And by car I mean no trucks or SUVs, but a sedan, coupe, etc. What would you suggest?
