Lots of options to choose from.. you can find used ones on ebay or stock or custom fabrications. Just Google it and pick one. All of the trim pieces can be bought pretty easily at a dealership or an online dealer like tascaparts.com.

The one in the install video looks pretty good. Should work with your white car too.

Don't know any US mfgs. Knightsport and Autoexe are the two high quality makers and are both Japanese.

This is the Knightsport grill of their full body kit. $$$
