^^ Well, it's gonna be a hassle to:
1) Buy some new headlight covers and swap them out, even if you don't want them.
2) Re-polish the exisiting headlight covers.
3) Transfer the title of car to a parent, then to you.
You just need to ask youself which is the least amount of hassle.
FYI, you cannot just get the clear plastic part of the lenses. It's all or none. Good luck and keep us updated on your decisions.
