ok, this is what I've had,

38 in a 30 = 3 points and a 60 quid fine
99 on the A3 near Guildford 6 points 150 quid
107 on the M25 at 3am on a Sunday morning, 28 day ban and 150 quid
69 (NIP) in a 50 (3 lane carriageway in Bagshot leading to the M3 that used to be a 70 limit) 3 points and a 60 quid fine.

Does your Mrs have a clean licence, what time of the day was it, what was the weather conditions, how was the traffic flow and most importantly, where did it happen?

This will be points and a small fine, I'm fairly sure.
