Not my own experience, some firends told me.
1. If he deicde to go to court, and decide to accept the guilty charge, but tell the judge he's short in cash, he may get a 50% discount in fine.
2. If he want to remove the points, he need to contact some ticket company, which will charge you more than $200, but it can remove your points. Which may keep his insurance unchanged.
I think the $175 for 139km/h should be in the highway (100km.h). If it's in a 60km/h city road, 139km/h is enough to put him into jael or revoke his license.
Good luck.
