After having been hit in my 91 and my 92, I'd never consider running without them.
With them, was minor repairs.
Without them, both cars would have been unrepairable and junked.
My opinion only.
I think I'm going to start buying bumpers. When the retarded trend of going bumperless is over, I'll sell them and retire in the Bahamas.
I wish I would have stocked up on hoods when rusting them was the trend of sheep.
