I've tried two times now to get Gold Chrome at the 30 car milestone, did the restart trick both times until I got it, and then it never appeared in my inventory. I've got no clue why, but it's seriously annoying, and I don't feel like risking it happening again.
So does anybody want to trade me for a Gold Chrome chip? Of the colors I assume are desirable, I've got:
Silver Chrome
Matte Dark Blue
Matte Light Blue
Matte Light Gray
Matte Dark Green
Matte White
Matte Gray
Matte Light Green
Matte Pink
Matte Orange
If there's something else, tell me and I'll see if I've got it.
