Most ive had issues with in the past if you explain that your not going to drive the car and if need be write them a letter stating that will allow u to drive cars out of work 3rd party.
I now just tell them althou im a painter i dont work in the motor trade as all i do at mclaren is spray/prep carbon SLR panels, and theres no way they'd let me drive one on my own insurance

plus any vans or company cars i drive on their insurance.
