Why I Hate Plastic Car Parts
Plastic bumpers are pretty common on cars nowadays and they aren't exactly as weak as some may think, and I don't think I've seen a BMW that had anymore plastic then that on the outside so this could just simply be the certain model problem also what's wrong with the door handles being made out of plastic? It will hold as long as the car will run that's for sure unless you'll really try to break them. Most of plastic components under the hood don't really require to be metal, and they last long enough, a lot of them probably never(as long as you keep your car) even break if handled properly and I'm pretty sure they aren't as hard or expensive to replace as their metal counterparts would be. Pretty much all vital components and the body itself is still made out of metal.
