The distinct irony is they caused far more monetary damage to their car than it would have cost just to rent a truck for the distance, or to have just bought the materials locally and rented a truck or driven several trips. Between driving the rear shocks through their upper mounts, essentially wrecking the sidewalls of both rear tires, probably bending the rear half-axle rather out of true, plus whatever structural damage appears to have been starting to the rear of the roof and those rear pillars. (I half expect they would have had the rear window actually blow out at some particularly nasty bump.) Of course, this last is assuming that the vehicle could actually move with all that concrete and the wood weighting the wheelwells down ONTO the rear tires like that.
