He's likely to get 100 quid fine and, depending on how lenient the judge is, 6 points - though these wont stop him from getting a license, but will remain on it. This means if he gets even one speeding fine, he'll lose his license.
Also, he'll be lumbered with an IN10 for the next 5years - so will probably face insurance companies hanging up on him left, right and centre, and will end up paying about 3k just to insure a 996cc panda.
Also, she'll maybe get done too, for letting him drive.
Serves him right. if its an absolutely non-descript car he must have been driving like a total fanny to get pulled.
