F1 Forensics is brought to thejudge13 readers in partnership with SomersF1, Like most of us, Matthew Somerfield has a day job and his is being the manager of a car & van rental company in the Isle of Wight.

Ask Somers anything you want in the comments section. He’s part of the crew now and hang’s out here regularly.
