Im sure this is technically insurance fraud.

I wasnt aware you could get another car driving on a 3rd party policy......

Plus im sure the wording in the policy will restrict your ability to drive another car in someone else name so you cant do it all the time

A simple observation by an insurance fraud investigator and you WILL get fucked

Im sure said barry boy will say "you cant prove nuffink bruv" well his step dad would have a hard time proving he paid for the car and mods and why he never drives it after simple investigation.

Also traders policys are for the trade...... so unless hes using it as a garage hack, or constantly on "test drives" im sure thats illegal too.
