I bought my car used, and it seems like it had taken some damage to the front bumper and undertray at some point (looks like it was mostly plastic).
The car is a 54 reg Corolla T3 2L diesel, and some of the hardware that is supposed to be holding the bumper/front in place seems to be missing (but then I'm only guessing at that). Especially, there are a couple of empty holes where the bumper cover and radiator cover connect to the metal that seem like they were meant to take bolts.
