Hmm learning something new everyday

The newer higher end cars have aluminum hoods.

The usual easy way to tell is by simply lifting the hood up, you will immediately notice the weight difference between them. Aluminum is much lighter.

Another fun fact, the M3's fender is plastic. However, i had a 2012 135 in my shop this past week and to my surprise that fender was not. lol
