Me and Alex have trade insurance as we have 4 cars and they change all the time

but we keep our own cars insured privatly for the gauanteed Value. Athought they do cover RS's as most don't but as Stu says you will pnly get trade value, hence us having out own cars insured. But I only pay £300 for mine with a garanteed value on a classic policy

In the long run it definatly works out cheaper for us having traders than insuring every car we own.
I think these days tho they are very strict who they give trade insurance to! We have had it years just said we was part time trading from home. Pay £600 a year for it
