Car Dealership

My husband has a acura tl dealer demo through his job but wants a new mustang gt. would i be aloud to drive the demo car at all the days he wants to drive the mustang? would the dealership allow that if i was insured to drive the demo through my own private insurance or is this off limits and only the employee can drive the car?

That would be completely up to the dealership. you need to ask them.
