Not sure about SMOG for CA, all imported cars I see now have to pay extra to be legal in CA.i find it odd too that for an imported JDM GC8 it would have a USDM rear bumper.
Appreciate that, I was about to post pictures of the other ones I found that had same bumper. Thanks for the information.That is a standard V1/2 bumper. The smooth bumpers we call "JDM bumpers" weren't until the V3+
Lot's of people forget that the earlier GCs were very different from the later ones.
