ok, I have 3 lost undertrays since my ownership. every single time I tired to find a nice condition used part replacement , either price was near as much as a brand new and in bad condition.

I really had no desire to pay like 100 dollars for a piece of plastic under my car the I will not appreciate its beauty but I still would like to have it for protection

so I went to get a piece of aluminum metal sheet at home-depot( hardware store in case of N America) ,I could not find a single piece of metal sheet like a car body wide and I cut my sheet in 2 and overlap in the middle

lifted up my car and traced the contour of bumper underneath. cut it .

drilled a few holes and secured with screw and plastic ties.

23 dollars of metal sheet and 10 minutes of my time.
