Really? I heard it was in this order: radiator, tires, engine and then glass.
I am pleased to acknowledge my hypocrisy by excepting from Waco-style attacks leftist pig vomit who have "moved beyond being Americans" and work to "bring it all down, man" or give aid and comfort to enemies no matter where the pig vomit are, mainstream media offices, universities, the street, or even Congress itself.
The door panels and the windows are pretty much invisible to .30 caliber rifle rounds.
Love the tagline BTW.

I think it depends on one's weaponry and objective.
Almost any shot to the radiator will limit a vehicle's useful range to a few miles. If the vehicle is approaching the shooter, the radiator is probably the largest target and so shooting it will be the most reliable way of ensuring the crooks can't just drive away as though nothing happened.
Shooting the tires will incapacitate a vehicle more quickly than shooting the radiator, but they're a smaller target and thus harder to hit.
Shooting the engine will stop an engine instantly *IF* the bullet reaches certain critical parts. Depending upon the weapon used, this may be likely or unlikely. A .50 Barett would probably have a decent chance of stopping an engine with one shot. A .22lr would be much less likely to do so. Intermediate firearms would offer intermediate odds.
Shooting at the occupants of the vehicle, of course, would incapacitate them (and thus the vehicle) immediately if a hit was scored, but depending upon jurisdiction may pose legal problems unless the occupants are directly threatening the defender with severe bodily harm.
Perhaps the best strategy would be to use a rifle with a telescopic scope and start by taking cover and shooting at the radiator. If one is shooting from behind cover, the attackers aren't likely to shoot accurately while their vehicle is moving, but a scope should allow the defender to see how they're reacting as their vehicle stops.
